In things which we know, everyone will trust us ... and we may do as we please, and no one will like to interfere with us; and we are free, and masters of others; and these things will be really ours, for we shall turn them to our good.
There are gems of wondrous brightness
Ofttimes lying at our feet,
And we pass them, walking thoughtless,
Down the busy, crowded street.
If we knew, our pace would slacken,
We would step more oft with care,
Lest our careless feet be treading
To the earth some jewel rare.
The necessity of knowing a little about a great many things is the most grievous burden of our day. It deprives us of leisure on the one hand, and of scholarship on the other.
The essential form of knowledge... is nothing but a representation of truth: for the truth of being and the truth of knowing are one, differing no more than the direct beam and the beam reflected.
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.
