Classicly

I propose, in this work, to examine phrenology as it appears in the writings of Gall, of Spurzheim, and of Broussais. My wish is to be brief. There is, however, one great secret in the art of being brief: it is to be clear. 

I frequently quote Descartes: I even go further; for I dedicate my work to his memory. I am writing in opposition to a bad philosophy, while I am endeavouring to recall a sound one.
