Nature is an endless combination and repetition of a very few laws. She hums the old well-known air through innumerable variations.
Ralph Waldo EmersonVivacity, leadership, must be had, and we are not allowed to be nice in choosing. We must fetch the pump with dirty water, if clean cannot be had.
Ralph Waldo EmersonTo wade in marshes and sea margins is the destiny of certain bird, and they are so accurately made for this that they are imprisoned in those places. Each animal out of its habitat would starve. To the physician, each man, each woman, is an amplification of one organ. A soldier, a locksmith, a bank-clerk, and a dancer could not exchange functions. And thus we are victims of adaptation.
