Thought and action must never part company.

The individual who has been liberated by reason is always running head-on into a world, a society, whose past in the shape of 'prejudices' has a great deal of power; he is forced to learn that past reality is also a reality.

The conflict between art and politics... cannot and must not be solved.

Psychologically speaking, one may say that the hypocrite is too ambitious; not only does he want to appear virtuous before others, he wants to convince himself.

A theology which is not based on revelation as a given reality but treats God as an idea would be as mad as a zoology which is no longer sure of the physical, tangible existence of animals.

Culture is being threatened when all worldly objects and things, produced by the present or the past, are treated as mere functions for the life process of society, as though they are there only to fulfill some need, and for this functionalization it is almost irrelevant whether the needs in question are of a high or a low order.
