The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.
Stephen Hawking
Celui qui cherche la vraie science doit la pêcher là où elle se trouve.
Michel de Montaigne
Unblemish'd let me live, or die unknown;
O grant an honest fame, or grant me none!
Alexander Pope
Scientists will always demarcate, beause part of what science an exclusion of some domains as irrelevant, rejected, outdated or incorrect.
Gordin - or Popper
Because too much thinking, unwavering autonomy, makes conforming to the administered world difficult and causes suffering, countless people project this suffering, which is in fact socially dictated, onto reason as such. Reason is supposed to have brought suffering and disaster into the world. The dialectic of enlightenment, which must indeed name the price of progress, all the ruin wrought by rationality in the form of increasing domination of nature, is in a sense broken off too soon, according to the model of a state of being whose blind impenetrability seems to block any way out. Thus the fact is willfully, desperately ignored that the excess of rationality, which the educated classes complain about and which they register in concepts such as mechanization, atomization, and massification, is a lack of rationality, namely the extreme form of all calculable apparatuses and means of domination at the expense of the goal, a rational human order… Rather than either positing rationality as an absolute or rejecting it as an absolute, reason must attempt to determine rationality itself as a moment within the totality, a moment which has admittedly become independent of this totality. Reason must become aware of its own essential natural character.

Adorno - Thinking
The truth is that the ideals we introduce into the subject matter of our science are not peculiar to it, nor are they produced by this science itself; rather they are the old, general types of human ideals.
Max Weber
