Obversely, however, the charm of the Platonic mode of thought, which was an ARISTOCRATIC mode, consisted precisely in RESISTANCE to obvious sense-evidence--perhaps among men who enjoyed even stronger and more fastidious senses than our contemporaries, but who knew how to find a higher triumph in remaining masters of them: and this by means of pale, cold, grey conceptional networks which they threw over the motley whirl of the senses--the mob of the senses, as Plato said.

In this overcoming of the world, and interpreting of the world in the manner of Plato, there was an ENJOYMENT different from that which the physicists of today offer us--and likewise the Darwinists and anti-teleologists among the physiological workers, with their principle of the "smallest possible effort," and the greatest possible blunder.

"Where there is nothing more to see or to grasp, there is also nothing more for men to do"-- that is certainly an imperative different from the Platonic one, but it may notwithstanding be the right imperative for a hardy, laborious race of machinists and bridge-builders of the future, who have nothing but ROUGH work to perform.

To study physiology with a clear conscience, one must insist on the fact that the sense-organs are not phenomena in the sense of the idealistic philosophy; as such they certainly could not be causes! Sensualism, therefore, at least as regulative hypothesis, if not as heuristic principle.

What?
And others say even that the external world is the work of our organs?
But then our body, as a part of this external world, would be the work of our organs! But then our organs themselves would be the work of our organs! It seems to me that this is a complete REDUCTIO AD ABSURDUM, if the conception CAUSA SUI is something fundamentally absurd.
