From each according to his abilities, to each according to his needs.
Capital is dead labor, which, vampire-like lives only by sucking living labor, and lives the more, the more labor it sucks.
Reason has always existed, but not always in a reasonable form.
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.

We cannot always choose the vocation to which we believe we are called. Our social relations, to some extent, have already begun to form before we are in a position to determine them.
When we have chosen the vocation in which we can contribute most to humanity, burdens cannot bend us because they are only sacrifices for all. Then we experience no meager, limited, egotistic joy, but our happiness belongs to millions, our deeds live on quietly but eternally effective, and glowing tears of noble men will fall on our ashes.
