Cavendish 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.
Humphry DavyConsistency in opinion is the slow poison of intellectual life, the destroyer of its vividness and energy.
Humphry DavyWhat is politeness in the home but the outcome of affection and self-respect, and the suppression of all those natural instincts of self-seeking that, allowed their way, produce the worst manners in the world?
Humphry DavyThe beginning of civilisation is the discovery of some useful arts, by which men acquire property, comforts, or luxuries. The necessity or desire of preserving them leads to laws and social institutions. The discovery of peculiar arts gives superiority to particular nations ... to subjugate other nations, who learn their arts, and ultimately adopt their manners;- so that in reality the origin as well as the progress and improvement of civil society is founded in mechanical and chemical inventions.
