Internal Variability

Famous quotes containing the words internal and/or variability:

“The real essence, the internal qualities, and constitution of even the meanest object, is hid from our view; something there is in every drop of water, every grain of sand, which it is beyond the power of human understanding to fathom or comprehend. But it is evident ... that we are influenced by false principles to that degree as to mistrust our senses, and think we know nothing of those things which we perfectly comprehend.”
—George Berkeley (1685–1753)

“The grand points in human nature are the same to-day they were a thousand years ago. The only variability in them is in expression, not in feature.”
