Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.
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.
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.
The universe must not be narrowed down to the limit of our understanding, but our understanding must be stretched and enlarged to take in the image of the universe as it is discovered.
But we are not dedicating or building any Capitol or Pyramid to human Pride, but found a holy temple in the human Intellect, on the model of the Universe... For whatever is worthy of Existence is worthy of Knowledge-which is the Image (or Echo) of Existence.
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.
