To say that the activity of science and art helps humanity's progress, if by that activity we mean the activity which now calls itself by those names, is as though one said that the clumsy, obstructive splashing of oars in a boat moving down stream assists the boat's progress. It only hinders it... The proof of this is seen in the confession made by men of science that the achievements of the arts and sciences are inaccessible to the labouring masses on account of the unequal distribution of wealth.

What then must we do? (1886)
