Production engineering

It is not a question of trying to reproduce objective features, only of good practice for the fingers and for the perceptive faculty, and that too is very useful. You must have read how Van Gogh was always getting his brother to send him drawings to copy. And how Rembrandt used to copy Indian an Italian pictures. Not of course, because they were short of material, but to get 'du corps'. So one should be always drawing... ...Oh, you’d love the Indians. The pure, Aryan Indians, not those one could see in Berlin, whose forms had become rigid and sterile through mingling with the Chinese.

To those who clamor, as many now do, "Produce! Produce!" one simple question may be addressed:—"Produce what?" ...What can be more childish than to urge the necessity that productive power should be increased, if part of the productive power which exists already is misapplied? Is not less production of futilities as important as, indeed a condition of, more production of things of moment? ... Yet this result of inequality ... cannot be prevented, or checked, or even recognized by a society which excludes the idea of purpose from its social arrangements and industrial activity.

The product of mental labor — science — always stands far below its value, because the labor-time necessary to reproduce it has no relation at all to the labor-time required for its original production.
