Seek first the virtues of the mind; and other things either will come, or will not be wanted.

It is not possible to run a course aright when the goal itself has not been rightly placed.

The logic now in use serves rather to fix and give stability to the errors which have their foundation in commonly received notions than to help the search for truth. So it does more harm than good.

They are ill discoverers that think there is no land, when they can see nothing but sea.

...it is the peculiar and perpetual error of the human understanding to be more moved and excited by affirmatives than by negatives...

Neither did the dispensation of God vary in the times after our Saviour came into the world; for our Saviour himself did first show His power to subdue ignorance, by His conference with the priests and doctors of the law, before He showed His power to subdue nature by His miracles. And the coming of this Holy Spirit was chiefly figured and expressed in the similitude and gift of tongues, which are but vehicula scientiæ.

The greatest error of all the rest is the mistaking or misplacing of the last or farthest end of knowledge: for men have entered into a desire of learning and knowledge, sometimes upon a natural curiosity and inquisitive appetite; sometimes to entertain their minds with variety and delight; sometimes for ornament and reputation; and sometimes to enable them to victory of wit and contradiction; and most times for lucre and profession; and seldom sincerely to give a true account of their gift of reason, to the benefit and use of men: as if there were sought in knowledge a couch whereupon to rest a searching and restless spirit; or a tarrasse, for a wandering and variable mind to walk up and down with a fair prospect; or a tower of state, for a proud mind to raise itself upon; or a fort or commanding ground, for strife and contention; or a shop, for profit or sale; and not a rich storehouse, for the glory of the Creator and the relief of man's estate.

The Idols of Tribe have their foundation in human nature itself, and in the tribe or race of men. For it is a false assertion that the sense of man is the measure of things. On the contrary, all perceptions as well of the sense as of the mind are according to the measure of the individual and not according to the measure of the universe. And the human understanding is like a false mirror, which, receiving rays irregularly, distorts and discolors the nature of things by mingling its own nature with it.

I could not be true and constant to the argument I handle, if I were not willing to go beyond others; but yet not more willing than to have others go beyond me again: which may the better appear by this, that I have propounded my opinions naked and unarmed, not seeking to preoccupate the liberty of men's judgments by confutations.

But by far the greatest obstacle to the progress of science and to the undertaking of new tasks and provinces therein is found in this - that men despair and think things impossible.

The cause and root of nearly all evils in the sciences is this - that while we falsely admire and extol the powers of the human mind we neglect to seek for its true helps.

But men must know that in this theater of man's life it is reserved only for God and angels to be lookers on.

The human understanding is moved by those things most which strike and enter the mind simultaneously and suddenly, and so fill the imagination; and then it feigns and supposes all other things to be somehow, though it cannot see how, similar to those few things by which it is surrounded.

We are wont to call that human reasoning which we apply to Nature the anticipation of Nature (as being rash and premature) and that which is properly deduced from things the interpretation of Nature.

It is manifest that there is no danger at all in the proportion or quantity of knowledge, how large soever, lest it should make it swell or out-compass itself; no, but it is merely the quality of knowledge, which, be it in quantity more or less, if it be taken without the true corrective thereof, hath in it some nature of venom or malignity, and some effects of that venom, which is ventosity or swelling. This corrective spice, the mixture whereof maketh knowledge so sovereign, is charity, which the Apostle immediately addeth to the former clause; for so he saith, "Knowledge bloweth up, but charity buildeth up".

The Idols of the Cave are the idols of the individual man. For everyone (besides the errors common to human nature in general) has a cave or den of his own, which refracts and discolors the light of nature, owing either to his own proper and peculiar nature; or to his education and conversation with others; or to the reading of books, and the authority of those whom he esteems and admires; or to the differences of impressions, accordingly as they take place in a mind preoccupied and predisposed or in a mind indifferent and settled; or the like. So that the spirit of man (according as it is meted out to different individuals) is in fact a thing variable and full of perturbation, and governed as it were by chance. Whence it was well observed by Heraclitus that men look for sciences in their own lesser worlds, and not in the greater or common world.

For the inquisition of Final Causes is barren, and like a virgin consecrated to God produces nothing.

The beginning is from God: for the business which is in hand, having the character of good so strongly impressed upon it, appears manifestly to proceed from God, who is the author of good, and the Father of Lights. Now in divine operations even the smallest beginnings lead of a certainty to their end. And as it was said of spiritual things, "The kingdom of God cometh not with observation," so is it in all the greater works of Divine Providence; everything glides on smoothly and noiselessly, and the work is fairly going on "before men are aware that it has begun. Nor should the prophecy of Daniel be forgotten, touching the last ages of the world: -"Many shall go to and fro, and knowledge shall be increased;" clearly intimating that the thorough passage of the world (which now by so many distant voyages seems to be accomplished, or in course of accomplishment), and the advancement of the sciences, are destined by fate, that is, by Divine Providence, to meet in the same age.

There are and can be only two ways of searching into and discovering truth. The one flies from the senses and particulars to the most general axioms, and from these principles, the truth of which it takes for settled and immovable, proceeds to judgment and to the discovery of middle axioms. And this way is now in fashion. The other derives axioms from the senses and particulars, rising by a gradual and unbroken ascent, so that it arrives at the most general axioms last of all. This is the true way, but as yet untried.

We are much beholden to Machiavel and others, that write what men do, and not what they ought to do.

The human understanding is unquiet; it cannot stop or rest, and still presses onward, but in vain. Therefore it is that we cannot conceive of any end or limit to the world, but always as of necessity it occurs to us that there is something beyond... But he is no less an unskilled and shallow philosopher who seeks causes of that which is most general, than he who in things subordinate and subaltern omits to do so.

Man, being the servant and interpreter of Nature, can do and understand so much and so much only as he has observed in fact or in thought of the course of nature. Beyond this he neither knows anything nor can do anything.

The sun, which passeth through pollutions and itself remains as pure as before.

There are also Idols formed by the intercourse and association of men with each other, which I call Idols of the Market Place, on account of the commerce and consort of men there. For it is by discourse that men associate, and words are imposed according to the apprehension of the vulgar. And therefore the ill and unfit choice of words wonderfully obstructs the understanding. Nor do the definitions or explanations wherewith in some things learned men are wont to guard and defend themselves, by any means set the matter right. But words plainly force and overrule the understanding, and throw all into confusion, and lead men away into numberless empty controversies and idle fancies.

He that defers his charity 'till he is dead, is (if a man weighs it rightly) rather liberal of another man's, than of his own.

For all knowledge and wonder (which is the seed of knowledge) is an impression of pleasure in itself.

Hurl your calumnies boldly; something is sure to stick.

For a man to love again where he is loved, it is the charity of publicans contracted by mutual profit and good offices; but to love a man's enemies is one of the cunningest points of the law of Christ, and an imitation of the divine nature.

Knowledge, that tendeth but to satisfaction, is but as a courtesan, which is for pleasure, and not for fruit or generation.

The law of nature teaches me to speak in my own defence: With respect to this charge of bribery I am as innocent as any man born on St. Innocents Day. I never had a bribe or reward in my eye or thought when pronouncing judgment or order. I am ready to make an oblation of myself to the King.

Let great authors have their due, as time, which is the author of authors, be not deprived of his due, which is, further and further to discover truth.

Credulity in arts and opinions is likewise of two kinds viz., when men give too much belief to arts themselves, or to certain authors in any art. The sciences that sway the imagination more than the reason are principally three viz., astrology, natural magic, and alchemy. Alchemy may be compared to the man who told his sons that he had left them gold, buried somewhere in his vineyard; while they by digging found no gold, but by turning up the mould about the roots of the vines procured a plentiful vintage. So the search and endeavours to make gold have brought many useful inventions to light.

I dare affirm in knowledge of nature, that a little natural philosophy, and the first entrance into it, doth dispose the opinion to atheism; but on the other side, much natural philosophy and wading deep into it, will bring about men's minds to religion; wherefore atheism every way seems to be combined with folly and ignorance, seeing nothing can can be more justly allotted to be the saying of fools than this, "There is no God" Of Atheism.

For I find that even those that have sought knowledge for itself and not for benefit, or ostentation, or any practical enablement in the course of their life, have nevertheless propounded to themselves a wrong mark, namely, satisfaction, which men call truth, and not operation. For as in the courts and services of princes and states, it is a much easier matter to give satisfaction than to do the business; so in the inquiring of causes and reasons it is much easier to find out such causes as will satisfy the mind of man, and quiet objections, than such causes as will direct him and give him light to new experiences and inventions.

My mind is calm, for my fortune is not my felicity. I know I have clean hands and a clean heart, and I hope a clean house for friends or servants; but Job himself, or whoever was the justest judge, by such hunting for matters against him as hath been used against me, may for a time seem foul, especially in a time when greatness is the mark and accusation is the game.

Time, which is the author of authors.

I bequeath my soul to God (...). My body to be buried obscurely. For my name and memory, I leave it to men's charitable speeches, and to foreign nations, and the next age.

"You err, not knowing the Scriptures nor the power of God" This canon is the mother of all canons against heresy; the causes of error are two; the ignorance of the will of God, and the ignorance or not sufficient consideration of his power.

Aristotle, a mere bond-servant to his logic, thereby rendering it contentious and well nigh useless.

Whence we see spiders, flies, or ants entombed and preserved forever in amber, a more than royal tomb.

Libraries are as the shrine where all the relics of the ancient saints, full of true virtue, and that without delusion or imposture, are preserved and reposed.

The two ways of contemplation are not unlike the two ways of action commonly spoken of by the ancients: the one plain and smooth in the beginning, and in the end impassable; the other rough and troublesome in the entrance, but after a while fair and even. So it is in contemplation: If a man will begin with certainties, he shall end in doubts; but if he will be content to begin with doubts he shall end in certainties.

It is true that may hold in these things, which is the general root of superstition; namely, that men observe when things hit, and not when they miss; and commit to memory the one, and forget and pass over the other.

Reading maketh a full man; conference a ready man; and writing an exact man.

Lucid intervals and happy pauses.

When you wander, as you often delight to do, you wander indeed, and give never such satisfaction as the curious time requires. This is not caused by any natural defect, but first for want of election, when you, having a large and fruitful mind, should not so much labour what to speak as to find what to leave unspoken. Rich soils are often to be weeded.

The monuments of wit survive the monuments of power.

Death is a friend of ours; and he that is not ready to entertain him is not at home.

Read not to contradict and confute, nor to believe and take for granted, nor to find talk and discourse, but to weigh and consider.

Nothing is terrible except fear itself.
