Beware lest any man cheat you by philosophy, and vain deceit; according to the tradition of men, according to the elements of the world, and not according to Christ:
Tertullian
When, again, he warns them to "beware of subtle words and philosophy," as being "a vain deceit," such as is "after the rudiments of the world" (not understanding thereby the mundane fabric of sky and earth, but worldly learning, and "the tradition of men," subtle in their speech and their philosophy), it would be tedious, and the proper subject of a separate work, to show how in this sentence (of the apostle's) all heresies are condemned, on the ground of their consisting of the resources of subtle speech and the rules of philosophy.
