James Vance May, Mental diseases: a public health problem
“ I cannot conceive anything more preposterously absurd than the attempt to classify diseases with all the divisions and technology of a botanical or zoological system, and to force what is essentially disorder and confusion to assume the appearance of that order and symmetry which nature displays in the arrangement of the organized world. An aetiological classification is the only mode of terminology and arrangement that can be of any practical advantage, and that is all that we have to consult. ”
