“There probably has to be a worldview for practical men who must be strong enough to get their hands dirty in political practice without getting dirty themselves, and even if they do, who cares? And a second worldview for youths, simpletons, women, and sensitive souls, for whom “purity” is just the right thing. One could call it a division of labor among temperaments.”

As quoted in Astrophysics of the Diffuse Universe (2003) by Michael A. Dopita and Ralph S. Sutherland
Context: Humanity needs practical men, who get the most out of their work, and, without forgetting the general good, safeguard their own interests. But humanity also needs dreamers, for whom the disinterested development of an enterprise is so captivating that it becomes impossible for them to devote their care to their own material profit. Without doubt, these dreamers do not deserve wealth, because they do not desire it. Even so, a well-organized society should assure to such workers the efficient means of accomplishing their task, in a life freed from material care and freely consecrated to research.
