DIRECTIONS FOR THE ATTAINMENT OF USEFUL KNOW- LEDGE. INTRODUCTION. No man is obliged to learn and know every thing; this can neither be sought nor required, for it is utterly impossible; yet all persons are under some obligation to improve their own understanding; otherwise it will be a barren desert, or a forest overgrown with weeds and brambles. Universal ignorance or infinite errors will overspread the mind which is utterly neglected, and lies without any cultivation. Skill in the sciences is indeed the business and pro- fession but of a small part of mankind; but there are many others placed in such an exalted rank in the world, as allows them much leisure and large opportunities to cultivate their reason, and to beautify and enrich their minds with various knowledge. Even the lower orders of men have particular callings in life, wherein they ought to acquire a just degree of skill; and this is not to be done well, without thinking and reasoning about them. The common duties and benefits of society, which be- long to every man living, as we are social creatures, and even our native and necessary relations to a family, i neighbourhood or government, oblige all persons what- ■ /; 6 INTRODUCTION. soever to use their reasoning powers upon a thousand occasions; every hour of hfe calls for some regular exer- cise of our judgment, as tatime and things, persons and actions: without a prudent and discreet determination in matters before us, we shall be plunged into perpetual errors in our conduct. Now that which should always be practised must at some time be learned. Besides, every son and daughter of Adam has a most important concern in the affairs of the life to come, and therefore it is a matter of the highest moment, for every one to understand, to judge, and to reason right about the things of religion. It is vain for any to say, we have no leisure time for it. The daily intervals of time, and vacancies from necessary labour, together with the one day in seven in the Christian world, allows sufficient time for this, if men would but apply themselves to it with half so much zeal and diligence as they do to the trifles and amusements of this life, and it would turn to infinitely better account. Thus it appears to be the necessary duty and the in- terest of every person living, to improve his understand- ing, to inform his judginent, to treasure up useful know- ledge, and to acquire the skill of good reasoning, as far as his station, capacity, and circumstances furnish him with proper means for it. Our mistakes in judgment may plunge us into much folly and guilt in practice. By acting without thought or reason, we dishonour the God that rflade us reasonable creatures, we often become injurious to our neighbours, kindred. Or friends, and we bring sin and misery upon ourselves; for we are accounta- ble to God, our judge, for every part of our irregular and mistaken conduct, where he hath given us sufficient ad- vantages to guard against those mistakes. CHAPTER I. GENERAL RULES FOR THE IMPROVEMENT OP KNOWLEDGE.* Rule 1. — Deeply possess your mind with the vast importance of a good judgment, and the rich and inesti- mable advantage of right reasoning. Review the in- stances of your own misconduct in life; think seriously with yourselves hov/ many follies and sorrows you had escaped, and how much guilt and misery you had pre- vented, if from your early years you had but taken due pains to judge aright concerning persons, times, and things. This v;ill awaken you with lively vigour to address yourselves to the work of improving your reason- ing powers, and seizing every opportunity and advantage for that end. II. Consider the weaknesses, frailties, and mistakes of human nature in general, which arise from the very con- stitution of a soul united to an animal body, and sub- jected to many inconveniences thereby. Consider the many additional weaknesses, mistakes, and frailties, which are derived from our original apostasy and fall from a state of innocence: how much our powers of un- derstanding are yet more darkened, enfeebled, and im- posed upon by our senses, our fancies, our unruly pas- sions, &c. Consider the depth and difficulty of many truths, and the flattering appearances of falsehood, whence arises an infinite variety of dangers to which we are exposed- in our judgment of things. Read with greediness those authors that treat of the doctrine of prejudices, prepossessions, and springs of error, on pur- pose to make your soul watchful on all sides, that it suf- fer itself, as far as possible, to be imposed upon, by none of them. III. A slight view of things so momentous is not suf- ficient. You should therefore contrive and practise some * Though the most of these following Rules are chiefly addressed to those whom their fortune or their station require to addict them- selves to the peculiar improvement of their minds in greater degrees of knowledge, yet every one who has leisure and opportunity to be acquamted with such writings as these, may find something among- them for their own wse. / 8 GENERAL RULES proper methods to acquaint yourself with your own igno- rance, and to impress your mind with a deep and pain- ful sense of the low and imperfect degrees of your present knowledge, that you may be incited with labour and activity to pursue after greater measures. Among others, you may find some such methods as these successful. 1. Take a wide survey now and then cf the vast and unlimited regions of learning. Let your meditations run over the names of all the sciences, w4th their numerous branchings, and innumerable particular themes of know- ledge; and then reflect how few of them you are aa quainted with in any tolerable degree. The most learned of mortals will never find occasion to act over again what is fabled of Alexander the Great, that when he had con- quered vvhat v/as called the eastern world, he wept for want of more worlds to conquer. The worlds of science are immense and endless. 2. Think what a numberless variety of questions and difficulties there are belonging even to that particular science in which you have made the greatest progress, and hov/ few of them there are in which you have ar- rived at a final and undoubted certainty; excepting only those questions in the pure and simple mathematics, w^hose theorems are demonstrable, and leave scarce any doubt; and yet, even in the pursuit of some few of these, mankind have been strangely bewildered. 3. Spend a few thoughts sometimes on the puzzling inquiries concerning vacuums and atoms, the doctrine of infinites, indivisibles, and incommensurables m ge- ometry, wherein there appear some insolvable difficul- ties: do this on purpose to give you a more sensible im- pression of the poverty of your understanding, and the imperfection of your knowledge. This will teach you what a vain thing it is to fancy that you know all things, and will instruct you to think modestly of your present attainments, wlien every dust of the earth, and every inch of empty space, surmounts your understanding, and triumphs over your presumption. Arithmo had been bred up to accounts all his life, and thought himself a complete master of numbers. But when he was pushed hard to give the square root of the number 2, he tried TO OBTAIN KNOWLEDGE. 9 at it, and laboured long in millesimal fractions, till he confessed there was no end of the inquiry; and yet he learned so much modesty by this perplexing question, that he was afraid to say it was an impossible thing. It is some good degree of improvement, when we are afraid to be positive. 4. Read the accounts of those vast treasures of know- ledge which some of the dead have possessed, and some of the living-do possess. Read and be astonished at the almost incredible advances which have been made in science. Acquaint yourself with some persons of great learning, that by converse among them, and comparing yourself with them, you may acquire a mean opinion of your own attainments,, and may thereby be animated with new zeal, to equal them as far as possible, or to ex- ceed: thus let your diligence be quickened by a generous and laudable emulation. If Vanillus had never met with Scitorio and Palydes, he had never imagined him- self a mere novice in philosophy, nor ever set himself to study in good earnest. Remember this, that if upon some few superficial acquirements you value, exalt, and swell yourself, as though you were a man of learning already, you are thereby building a most unpassable barrier against all improvement; you will lie down and indulge idleness, and rest yourself contented in the midst of deep and shameful ignorance. Multi ad scientiam pervenissent si se illuc pervenisse non putassent. IV. Presume not too much upon a bright genius, a ready wit, and good parts; for this, without labour and study, will never make a man of knowledge and wisdom. This has been an unhappy temptation to persons of a vigorous and gay fancy, to despise learning and study. They have been acknowledged to shine in an assembly, and sparkle in a discourse on common topics, and thence they took it into their heads to abandon reading and labour, and grow old in ignorance; but when they had lost their vivacity of animal nature and youth, they be- came stupid and sottish even to contempt and ridicule. Lucidus and Scintillo are young men of this stamp; they shine in conversation; they spread their native riches iO GENERAL RULES before the ignorant; they pride themselves in their own lively images of fancy, and imagine themselves wise and learned; but they had best avoid the presence of the skilful, and the test of reasoning; and I would advise them once a day to think forward a little, what a con- temptible figure they will make in age. The witty men sometimes have sense enough to know their own foible; and therefore they craftily shun the attacks of argument, or boldly pretend to despise and renounce them, because they are conscious of their own ignorance, and inwardly confess their want of acquaint- ance with the skill of reasoning. V. As you are not to fancy yourself a learned man because you are blessed with a ready wit; so neither must you imagine that large an^ laborious reading, and a strong memory, can denominate you truly wise. What that excellent critic has determined when he decided the question, whether wit or study makes the best poet, may well be applied to every sort of learning; ...... Ego nee studi'um sine divite vena, Tfec rude quid prosit,, video, ingenium: alterius sic Altera poscit opem res, et conjurat amice. Hor. de Art. Poet. Thus made English: Concerning poets there has been contest. Whether they're made by art or nature best; But if I may presume in this affair, Among the rest my judgment to declare, No art without a genius will avail. And parts without the help of art will fail: But both ingredients jointly must unite. Or verse will never shine with a transcendent light. Oldham, It is meditation and studious thought, it is the exer- cise of your own reason and judgment upon all you read, that gives good sense even to the best genius, and afforda your understanding the truest improvement. A boy of a strong memory may repeat a Vi^hole book of Euclid, yet be no geometrician; for he may not be able perhaps to demonstrate one single theorem. Memorino has learned half the Bible by heart, and is become a living concordance, and a speaking index to theological folios, and yet lie understands little of divinity. TO OBTAIM KNOWLEDGE. 11 A well furnished library, and a capacious memory, are indeed of singular use toward the improvement of the mind; but if all your learning be nothing else but a mere amassment of what others have written, without a due penetration into the meaning, and without a judi- cious choice and determination of your own sentiments, I do not see what title your head has to true learning above your shelves. Though you have read philosophy and theology, morals and metaphysics in abundance, and every other art and science, yet if your memory is the only faculty employed, with the neglect of your rea- soning powers, you can justly claim no higher character but that of a good historian of the sciences. Here note, many of the foregoing advices are more peculiarly proper for those who are conceited of their abilities, and are ready to entertain a high opinion of themselves. But a modest, humble youth, of a good genius, should not suffer himself to be discouraged by any of these considerations. They are designed only as a spur to diligence, and a guard against vanity and pride. VI. Be not so weak as to imagine, that a life of learn- ing is a life of laziness and ease; dare not give up your- self to any of the learned professions, unless you are resolved to labour hard at study, and can make it your delight, and the joy of your life, according to the motto of our late Lord Chancellor King: .... Labor ipse voluptas. It is no idle thing to be a scholar indeed. A man much addicted to luxury and pleasure, recreation and pastime, should never pretend to devote himself entirely to the sciences, unless his soul be so reformed and refined, that he can taste all these entertainments eminently in his closet, among his books and papers. Sobrino is a temperate man, and a philosopher, and he feeds upon partridge and pheasant, venison and ragouts, and every delicacy, in a growing understanding, and a serene and healthy soul, though he dines on a dish of sprouts or turnips. Languinos loved his ease, and therefore chose to be brought up a scholar; he had much indolence in his temper; and as he never cared for study, he falls > 12 GENERAL RULES under universal contempt in his profession, because he has nothing but the gown and the name. VII. Let the hope of new discoveries, as well as the satisfaction and pleasure of known truths, animate your daily industry. Do not think learning in general is ar- rived at its perfection, or that the knowledge of any par- ticular subject in any science cannot be improved, mere- ly because it has lain five hundred or a thousand years without improvement. The present age, by the bless- ing of God on the ingenuity and diligence of men, has brought to light such truths in natural philosophy, and such discoveries in the heavens and the earth, as seemed to be beyond the reach of man. But may there not be Sir Isaac Newtons in every science? You should never despair therefore of finding out that which has never yet been found, unless you see something in the nature of it which renders it unsearchable, and above the reach of our faculties. Nor should a student in divinity imagine that our age is arrived at a full understanding of every thing which can be known by the Scriptures. Every age since the Reformation hath thrown some further light on difficult texts and paragraphs of the Bible, which have been long obscured by the early rise of antichrist: and since there are at present many difficulties and darknesses hanging about certain truths of the Christian religion, and since several of these relate to important doctrines, such as the origin of sin, the falj of Adam, the person of Christ, the blessed Trinity, and decrees of God, &c. which do still embarrass the minds of honest and inquiring rea- ders, and which make work for noisy controversy; it is certain there are several things in the Bible yet un- known, and not sufficiently explained; and it is certain that there is some way to solve these difficulties, and to reconcile these seeming contradictions. And why may not a sincere searcher of truth in the present age, by la- bour, diligence, study, and prayer, with the best use of his reasoning powers, find out the proper solution of those knots and perplexities which have hitherto been imsolved, and which have affijrded matter for angry quarrelUng? Happy is every man who shall be favoured TO OBTAIN KNOWLEDGE. IS of Heaven, to give a helping hand towards the intro- duction of the blessed age of hght and love. VIII. Do not hover always on the surface of things, nor take up suddenly with mere appearances; but pene- trate into the depth of matters, as far as your time and circumstances allow, especially in those things which re- late to your own profession. Do not indulge yourselves to judge of things by the first glimpse, or a short and su- perficial view of them; for this will fill the mind with errors and prejudices, and give it a wrong turn and ill habit of thinking, and make much work for retraction Subito is carried away with title pages, so that he ven- tures to pronounce upon a large octavo at once, and to recommend it wonderfully when he has read half the preface. Another volume of controversies, of equal size, was disbarded by him at once, because it pretended to treat of the Trinity, and yet he could neither find the word essence nor subsistehcies in the twelve first pages; but Subito changes his opinions of men and books and things so often, that nobody regards him. As for those sciences, or those parts of knowledge^ which either your profession, your leisure, your inclina~ tion, or your incapacity, forbid you to pursue with much application, or to search far into them, you must be con- tented with an historical and superficial knowledge of them, and not pretend to form any judgment of your own on those subjects which you understand very im- perfectly. IX. Once a day, especially in the early years of life and study, call yourselves to an account what new ideas, what new proposition or truth you have gained, what further confirmation of known truths, and what ad- vances you have made in any part of knowledge; and let no day, if possible, pass away without some intellec- tual gain: sucK a course, well pursued, must certainly advance us in useful knowledge. It is a wise proverb among the learned, borrowed from the lips and practice of a celebrated painter. Nulla dies sine linea, " Let no day pass without one line at least;" and it was a sacred rule among the Pythagoreans, That they should everj evening thrice run over the actions and affairs of 2 14 GENERAL RULES day, and examine what their conduct had been, what they had done, or what they had neglected: and they assured their pupils, that by this method they would make a noble progress in the path of virtue. My^S VTTvov fixXaKOia-iv cti^ Oftficta-i yr^OFSs^aa-dsii 11)} TTu^s^yivi ri S' £g£^a; t» fiot Seov oux' eTeXeaSyi; TauTc* )s dsiyjg UQiTf^g iig <%v<» 5->;o-s*, Nor let soft slumber close your eyes, Before youVe recollected thrice The train of action through the day; Where have my feet chose out their way? What have I learn 'd, where'er I've been, From all I've heard, from all I've seen? What know I more that's worth the knowing? What have I done that's worth the doing? What have I sought that I should shun? What duty have I left undone? Or into what new follies run? These self-inquiries are the road That leads to virtue, and to God. I would be glad, among a nation of Christians, to find young men heartily engaged in the practice of what this heathen writer teaches. X. Maintain a constant watch at all times against a dogmatical spirit: fix not your assent to any proposition in a firm and unalterable manner, till you have some firm and unalterable ground for it, and till you have ar- rived at some clear and sure evidence; till you have turned the proposition on all sides, and searched the matter through and through, so that you cannot be mis- taken. And even where you may think you have full grounds of assurance, be not too early, nor too frequent, in expressing this assurance in too peremptory and posi- tive a manner, remembering that human nature is al- ways liable to mistake in this corrupt and feeble state. A dogmatical spirit has many inconveniences attending it: as 1. It stops the ear against all further reasoning upon that subject, and shuts up the mind from all further im- provements of knowledge. If you have resolutely fixed your opinion, though it be upon too slight and insuffi- cient grounds, yet you will stand determined to renounce the strongest reason brought for the contrary opinion, TO OBTAIN KNOWLEDGE. 16 and grow obstinate against the force of the clearest ar- gument. Positivo is a man of this character; and has often pronounced his assurance of the Cartesian vor- texes: last year some further light broke in upon his un- derstanding, with uncontrollable force, by reading some- thing of mathematical philosophy; yet having asserted his former opinions in a most confident manner, he is tempted now to wink a little against the truth, or to prevaricate in his discourse upon that subject, lest by admitting conviction, he should expose himself to the necessity of confessing his former folly and mistake: and he has not humility enough for that. 2. A dogmatical spirit naturally leads us to arrogance of mind, and gives a man some airs in conversation which are too haughty and assuming. Audens is a man of learning, and very good company; but his infallible assurance renders his carriage sometimes insupportable. A dogmatical spirit inclines a man to be censorious of his neighbours. Every one of his own opinions appears to him written as it were with sunbeams; and he grows angry that his neighbour does not see it in the same light. He is tempted to disdain his correspondents, as men of a low and dark understanding, because they will not believe what he does. Furio goes further in this wild track; and charges those who refuse his notions with wilful obstinacy and vile hypocrisy; he tells them boldly, that they resist the truth, and sin against their consciences. These are the men that, when they deal in contro- versy, delight in reproaches. They abound in tossing about absurdity and stupidity among their brethren; they cast the imputation of heresy and nonsense plenti- fully upon their antagonists: and in matters of sacred importance, they deal out their anathemas in abun- dance upon Christians better than themselves; they de- nounce damnation upon their neighbours, without either justice or mercy; and when they pronounce sentences of divine wrath against supposed heretics, they add their own human fire and indignation. A dogmatist in religion is not a great way off from a bigot, and is in high danger of growing up to be a bloody persecutor^,. 16 GENERAL RULES XI. Though caution and slow assent will guard you against frequent mistakes and retractions; yet you should get humility and courage enough to retract any mistake, and confess an error: frequent changes are tokens of le- vity in our first determinations; yet you should never be too proud to change your opinion, nor frightened at the name of changeling. Learn to scorn those vulgar bug- bears, which confirm foolish man in his old mistakes, for fear of being charged with inconstancy. I confess it is better not to judge, than to judge falsely; it is wiser to withhold our assent till we see complete evidence; but if we have too suddenly given up our assent, as the wisest man does sometimes, if we have professed what we find afterwards to be false, we should never be ashamed nor afraid to renounce a mistake. That is a noble essay which is found among the occasional papers " to encour- age the world to practise retractations;" and I would re- commend it to the perusal of every scholar and every Christian. XII. He that would raise his judgment above the vul- gar rank of mankind, and learn to pass a just sentence on persons and things, must take heed of a fanciful tem- per of mind, and a humorous conduct in his affairs. Fancy and humour, early and constantly indulged, may expect an old age overrun with follies. The notion of a humourist is one that is greatly pleased, or greatly displeased with little things; who sets his heart much upon matters of very small importance; who has his will determined every day by trifles, his actions sel- dom directed by the reason and nature of things, and his passions freque'ntly raised by things of little moment. Where this practice is allowed, it v/ill insensibly warp the judgment to pronounce little things great, and tempt you to lay a great weight upon them. In short, this temper will incline you to pass an unjust value on almost every thing that occurs; and every step you take in this path is just so far out of the way to wisdom. XIII. For the same reason have a care of trifling with things important and momentous, or of sporting vyith things awful and sacred: do not indulge a spirit of ridi^ cule, as some witty men do on all occasions and subjects. TO OBTAIN KNOWLEDGE. H This will as unhappily bias the judgment on the othei side, and inchne you to pass a low esteem on the most valuable objects. Whatsoever evil habit we indulge in practice, it will insensibly obtain a power over our un- derstanding, and betray us into many errors. Jocander is ready with his jests to answer every thing that he hears; he reads books in the same jovial humour, and has gotten the art of turning every thought and sentence into mer- riment. How many awkward and irregular judgments does this man pass upon solemn subjects even when he designs to be grave and in earnest! His mirth and laugh- ing humour is formed into habit and temper, and leads his understanding shamefully astray. You will see him wandering in pursuit of a gay flying feather, and he is drawn by a sort of ignis fatuus into bogs and mire almost every day of his life. XIV. Ever maintain a virtuous and pious frame of spirit; for an indulgence of vicious inclinations debases the understanding and perverts the judgment. Whore- dom and wine, and new wine, take away the heart and soul, and reason of a man. Sensuality ruins the better faculties of the mind; an indulgence to appetite and pas- sion enfeebles the powers of reason; it makes the judg- ment weak and susceptible of every falsehood, and espe- cially of such mistakes as have a tendency towards the gratification of the animal: and it warps the soul aside strangely from that steadfast honesty and integrity that necessarily belongs to the pursuit of truth. It is the vir- tuous man who is in a fair way to wisdom. " God gives to those that are good in his sight wisdom, and know- ledge, and joy," Eccles. ii. 26. Piety towards God, as well as sobriety and virtue, are necessary qualifications to make a truly wise and judi- cious man. He that abandons religion must act in such a contradiction to his own conscience and best judgment, that he abuses and spoils the faculty itself. It is thus in the nature of things, and it is thus by the righteous judg- ment of God: even the pretended sages among the hea- thens, who did not like to retain God in their knowledge, they were given up to a reprobate mind, ei? vow aJoxi^ov, an undistinguishing or injudicious mind, so that they 2* 18 GENERAL RULES judged inconsistently, and practised mere absurditieSj TK i/.v[ xyyiy.ovTUy JvOm. 1. 28. And it is the character of the slaAi'es of antichrist, 2 Thess. ii. 10, &c. that those "who receive not the love of the truth were exposed to the power of diabolical sleights and lying wonders." When divine revelation shines and blazes in the face of men with glorious evi- dence, and they wink their eyes against it, the god of this world is suffered to blind them, even in the most ob- ^ vious, common, and sensible things. The great God of Heaven, for this cause, sends them strong delusions, that they should believe a lie; and tlie nonsense of transub- stantiation, in the popish world, is a most glaring accom- plishment of this prophecy, beyond even what could have been thought of or expected among creatures who pre- tend to reason. XV. Watch against the pride of your own reason, and a vain conceit of your own intellectual powers, with the neglect of divine aid and blessing. Presame not upon great attainments in knowledge by your own self-suffi- ciency: those who trust to their own understandings en- tirely are pronounced fools in the word of God; and it iss the wisest of men gives them this character. " He that trusteth in his own heart is a fool," Proy. xxviii. 26. And the same divine writer advises us to " trust in the Lord with all our heart, and not to lean to our under- standings, nor to be wise in our own eyes," chap. iii. 5. 7, Those who, with a neglect of religion and dependence on God, apply themselves to search out every article in the things of God by the mere dint of their own reason, have been suffered to run into wild excesses of foolery, and strange extravagance of opinions. Every one who' pursues this vain course, and will not ask for the conduct of God in the study of religion, has just reason to fear he shall be left of God, and given up a prey to a thousand prejudices; that he shall be consigned over to the follies of his own heart, and pursue his own temporal and eter™ nal ruin. And even in common studies we should, by humility and dependence, engage the God of truth oit our side. XVI. Offer up, therefore, your daily requests to God TO OBTAIN KNOWLEDGE. 19 the father of lights, that he would bless all your attempts and labours in reading, study, and conversation. Think with yourself how easily and how insensibly, by one turn of thought, he can lead you into a large scene of useful ideas: he can teach you to lay hold on a clue which ma}'^ guide your thoughts with safety and ease through all the difficulties of an intricate subject. Thinit how easily the Author of your beings can direct your motions, by his providence, so that the glance of an eye, or a word striking the ear, or a sudden turn of the fancy, shall con- duct you to a train of happy sentiments. By his secret and supreme method of government, he can draw you to read such a treatise, or converse with such a person, who may give you more light into some deep subject in an hour, than you could obtain by a month of your own solitar}'^ labour. Think with yourself with how much ease the God of spirits can cast into your minds some useful suggestion, and give a happy turn to your own thoughts, or the thoughts of those with whom you converse, whence you may derive unspeaka,ble light and satisfaction, in a mat- ter that has long puzzled and entangled you: he can show you a path which the vulture's eye has not seen, and lead you by some unknown gate or portal, out of a wilderness and labyrinth of difficulties, wherein you have been long wandering. Implore constantly his divine grace to point your in- clination to proper studies, and to fix your heart there. He can keep off temptations on the right hand, and on the left, both by the course of his providence, and by the secret and insensible intimations of his Spirit. He can guard your understandings from every evil influence of error, and secure you from the danger of evil books and men, which might otherwise have a fatal effect, and lead you into pernicious mistakes. Nor let this sort of advice fall under the censure of the godless and profane, as a mere piece of bigotry or enthusiasm, derived from faith and the Bible: for the reasons which I have given to support this pious prac- tice, of invoking the blessing of God on our studies, are derived from the light of nature as well as revelation 20 GENERAL RULES, &C. He that made our souls, and is the Father of spirits, shall he not be supposed to have a most friendly influ- ence toward the instruction and government of them? The Author of our rational powers can involve them in darkness when he pleases, by a sudden distemper; or he can abandon them to wander into dark and foolish opinions, when they are filled with a vain conceit of their own light. He expects to be acknowledged in the common affairs of life; and he does as certainly expect it in the superior operations of the mind, and in the search of knowledge and truth. The very Greek heathens, by the light of reason, were taught to say, 'Ex A(os tigxoy.s
