All that is made perfect by progress perishes also by progress.

All is war.

War is the supreme drama of a completely mechanized society.

Self-conceit is the enemy of progress.

If civilization has an opposite, it is war.

Has not authority from time immemorial stamped every step of progress as treasonable?

Progress just means bad things happen faster.

All war presupposes human weakness and seeks to exploit it.

There can be no progress without head-on confrontation.

the major advances in civilization are processes that all but wreck the societies in which they occur

A system which in every act of its life sacrifices the welfare of large sections of the people, yes, of whole nations, to the selfish lust for power and the economic interests of small minorities must of necessity dissolve all social ties and lead to a constant war of all against all.

Comfort is the enemy of progress.

There is no advance without strife.

The ambiguity of progress becomes evident. Without doubt, it offers new possibilities for good, but it also opens up appalling possibilities for evil — possibilities that formerly did not exist. We have all witnessed the way in which progress, in the wrong hands, can become and has indeed become a terrifying progress in evil. If technical progress is not matched by corresponding progress in man's ethical formation, in man's inner growth (cf. Eph 3:16; 2 Cor 4:16), then it is not progress at all, but a threat for man and for the world.
