" Sensation is unorganized stimulus, perception is organized sensation, conception is organized perception, science is organized knowledge, wisdom is organized life: each is a greater degree of order, and sequence, and unity.

Whence this order, this sequence, this unity?

Not from the things themselves; for they are known to us only by sensation that come through a thousand channels at once in disorderly multitude; it is our purpose that put order and sequence and unity upon this importunate lawlessness; it is ourselves, our personalities, our minds, that bring light upon these seas. "
