What counts can't always be counted; what can be counted doesn't always count.

I see in Nature a magnificent structure... that must fill a thinking person with a feeling of humility.

Capitalism creates a huge community of producers who are unceasingly striving to deprive each other of the fruits of their collective labor, and an oligarchy that cannot be effectively checked even by a democratically organized society....the subjugation is not by force but because the privileged class has long ago established a system of values by which the people were thenceforth, to a large extent unconsciously, guided in their social behavior.
