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.
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
The human understanding, when any preposition has been once laid down... forces everything else to add fresh support and confirmation; and although more cogent and abundant instances may exist to the contrary, yet it either does not observe them or it despises them, or it gets rid of and rejects them by some distinction, with violent and injurious prejudice, rather than sacrifice the authority of its first conclusions.
Lastly, I would address one general admonition to all: that they consider what are the true ends of knowledge, and that they seek it not either for pleasure of the mind, or for contention, or for superiority to others, or for profit, or fame, or power, or any of these inferior things: but for the benefit and use of life; and that they perfect and govern it in charity.
The great advantages of simulation and dissimulation are three. First to lay asleep opposition and to surprise. For where a man's intentions are published, it is an alarum to call up all that are against them. The second is to reserve a man's self a fair retreat: for if a man engage himself, by a manifest declaration, he must go through, or take a fall. The third is, the better to discover the mind of another. For to him that opens himself, men will hardly show themselves adverse; but will fair let him go on, and turn their freedom of speech to freedom of thought.
There is a cunning which we in England call "the turning of the cat" in the pan; which is, when that which a man says to another, he says it as if another had said it to him.
I'll follow, as they say, for reward. He that rewards me, God reward him. If I do grow great, I'll grow less; for I'll purge, and leave sack, and live cleanly, as a nobleman should do.
