The Nuremberg Trial of the German war criminals was tacitly based on the recognition of the principle: criminal actions cannot be excused if committed on government orders; conscience supersedes the authority of the law of the state.

I am not a positivist. Positivism states that what cannot be observed does not exist.

One would have to say 'only what we observe exists,' which is obviously false.

It is better to believe than to disbelieve; in doing you bring everything to the realm of possibility.

Science can only ascertain what is, but not what should be, and outside of its domain value judgements of all kinds remain necessary.
