The pest of society are the egotist, they are dull and bright, sacred and profane, course and fine. It is a disease that like the flu falls on all constitutions.
Ralph Waldo EmersonThe mind is a finer body, and resumes its functions of feeding, digesting, absorbing, excluding, and generating, in a new and ethereal element. Here, in the brain, is all the process of alimentation repeated, in the acquiring, comparing, digesting, and assimilating of experience. Here again is the mystery of generation repeated.
Ralph Waldo Emerson
