Karl Marx on ideas

Philosophy is to the real world as masturbation is to sex.

Every act and event is the inevitable result of prior acts and events and is independent of human will.

The more man puts into God, the less he retains in himself. The worker puts his life into the object; but now his life no longer belongs to him, but to the object.

Great minds discuss ideas. Average minds discuss events. Small minds discuss people.

Eleanor Roosevelt1884–1962

It is the mark of an educated mind to be able to entertain a thought without accepting it.

One resists the invasion of armies; one does not resist the invasion of ideas.
