You shouldn't say it is not good. You should say you do not like it; and then, you know, you're perfectly safe.

It is not necessary to accept everything as true, one must only accept it as necessary

Respect for the truth does not require one to take seriously ideas simply because they are popular or backed by influential people. Once it has become clear that a proposal makes no contribution to our understanding, we are not compelled by tolerance to give it further attention.

It is bad if you praise, and worse if you reprove a thing, I mean, if you do not understand the matter well.

Everything you say should be true, but not everything true should be said.

To me, bad taste is what entertainment is all about. If someone vomits watching one of my films, it's like getting a standing ovation. But one must remember that there is such a thing as good bad taste and bad bad taste. it's easy to disgust someone; I could make a ninety-minute film of people getting their limbs hacked off, but this would only be bad bad taste and not very stylish or original. To understand bad taste one must have very good taste. Good bad taste can be creatively nauseating but must, at the same time, appeal to the especially twisted sense of humor, which is anything but universal.

A good tale evil told were better untold, and an evil take well told need none other solicitor.

What I have in mind is that art may be bad, good, or indifferent, but, whatever adjective is used, we must call it art, and bad art is art in the same way that a bad emotion is still an emotion.

Conceptions of good and bad are all mental speculations. Therefore, it is erroneous to say, "this is good" and "this is bad".

A true thing, poorly expressed, is a lie.

It is an impressively arrogant move to conclude that just because you don't like something, it is empirically not good.

Wide acceptance of a quote is not the proof of its validity

No idea is really bad, unless we are uncritical. What is really bad is to have no idea at all.
