A moment is a concentrated eternity.

The primary wisdom is intuition.

Nature forever puts a premium on reality. What is done for effect is seen to be done for effect; what is done for love is felt to be done for love. A man inspires affection and honor because he was not lying in wait for these.

Nature is a rag-merchant, who works up every shred and ort and end into new creations; like a good chemist, whom I found, the other day, in his laboratory, converting his old shirts into pure white sugar.

Science is nothing but the finding of analogy, identity, in the most remote parts.

Men admire the man who can organize their wishes and thoughts in stone and wood and steel and brass.

Sometimes a scream is better than a thesis.
