There is a difference between happiness and wisdom: he that thinks himself the happiest man is really so; but he that thinks himself the wisest is generally the greatest fool.
It is true, that a little philosophy inclineth man’s mind to atheism; but depth in philosophy bringeth men’s minds about to religion. For while the mind of man looketh upon second causes scattered, it may sometimes rest in them, and go no further; but when it beholdeth the chain of them, confederate and linked together, it must needs fly to Providence and Deity.
When a bee stings, she dies. She cannot sting and live. When men sting, their better selves die. Every sting kills a better instinct. Men must not turn bees and kill themselves in stinging others.
A man cannot speak to his son, but as a father; to his wife, but as a husband; to his enemy, but upon terms: whereas a friend may speak, as the case requires, and not as it sorteth with the person.
Another error is an impatience of doubt and haste to assertion without due and mature suspension of judgment. For 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.
A man that hath no virtue in himself, ever envieth virtue in others. For men's minds, will either feed upon their own good, or upon others' evil; and who wanteth the one, will prey upon the other; and whoso is out of hope, to attain to another's virtue, will seek to come at even hand, by depressing another's fortune.
Crafty men condemn studies; Simple men admire them; And wise men use them: For they teach not their own use: but that is a wisdom without them, and above them, won by observation.
If any human being earnestly desire to push on to new discoveries instead of just retaining and using the old; to win victories over Nature as a worker rather than over hostile critics as a disputant; to attain, in fact, clear and demonstrative knowlegde instead of attractive and probable theory; we invite him as a true son of Science to join our ranks.
But I account the use that a man should seek of the publishing of his own writings before his death, to be but an untimely anticipation of that which is proper to follow a man, and not to go along with him.
Take an arrow, and hold it in flame for the space of ten pulses, and when it cometh forth you shall find those parts of the arrow which were on the outsides of the flame more burned, blacked, and turned almost to coal, whereas the midst of the flame will be as if the fire had scarce touched it. This is an instance of great consequence for the discovery of the nature of flame; and sheweth manifestly, that flame burneth more violently towards the sides than in the midst.
