"From mechanics in rest and motion to the relation of sensation and thought there is a uniform progression of interruptions." With this assurance Herr Duehring spares himself from saying anything further about the origin of life, though one might reasonably expect that a thinker who has followed the development of the world from its self-contained condition, and who is so much at home with the other heavenly bodies would be here at home also. Besides this assurance is only half true in so far as it is not yet completed by means of the log line of Hegel, of which mention has been made already. In all its gradations the transition from one form of evolution to another remains a leap, a differentiating movement. So in the transition from the mechanics of the worlds to those of the smaller amounts of matter in each single world, just so also in that from the mechanics of the mass to that of the molecule—the motion which we examine particularly in physics, so-called, heat, light, electricity, magnetism, just in the same way also the transition from the physics of the molecule to the physics of the chemical atom is completed by a differentiating leap, and it is just the same with the transition from ordinary chemical action to the chemistry of albumen which we call life. Within the sphere of life the changes become less frequent and less remarkable. Therefore Hegel must again correct Herr Duehring.

The idea of purpose furnishes Herr Duehring with his conception of the transition to the organic world. This is again borrowed from Hegel, who in his "logic"—teachings of the concept—mingled with teachings of teleology or of purpose, passes over from chemistry to life. Whichever way we look we discover Herr Duehring to
