Humphry DavyConsistency in opinion is the slow poison of intellectual life, the destroyer of its vividness and energy.
Humphry DavyNature is beautiful, and you are in her bosom.

Humphry DavyCavendish was a great Man with extraordinary singularities-His voice was squeaking his manner nervous He was afraid of strangers & seemed when embarrassed to articulate with difficulty-He wore the costume of our grandfathers. Was enormously rich but made no use of his wealth... He Cavendish lived latterly the life of a solitary, came to the Club dinner & to the Royal Society: but received nobody at his home. He was acute sagacious & profound & I think the most accomplished British Philosopher of his time.
