``By this it appears how necessary it is for any man that aspires to true knowledge to examine the definitions of former authors.... For the errors of definitions multiply themselves, according as the reckoning proceeds, and lead men into absurdities, which at last they see, but cannot avoid, without reckoning anew from the beginning; in which lies the foundation of their errors.'' --- Thomas Hobbes, \textit{Leviathan}
