It is wrong for a man to say that he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty.
Thomas HuxleyRead
It is not to be forgotten that what we call rational grounds for our beliefs are often extremely irrational attempts to justify our instincts.
Interpretation
Our beliefs often stem from irrational foundations, masked as rational justifications.
In this quote, Thomas Huxley suggests that what we perceive as rational justifications for our beliefs may actually be rooted in instinctual and emotional responses. This reflects a deeper understanding of human psychology, where our reasoning can sometimes serve to validate feelings or impulses that we may not consciously acknowledge as irrational.

We are all as much extraordinary phenomena of nature as trees, clouds, the patterns in running water, the flickering of fire, the arrangement of the stars and the form of a galaxy.
A turkey is more occult and awful than all the angels and archangels. In so far as God has partly revealed to us an angelic world, he has partly told us what an angel means. But God has never told us what a turkey means. And if you go and stare at a live turkey for an hour or two, you will find by the end of it that the enigma has rather increased than diminished.
Totalitarianism is never content to rule by external means, namely, through the state and a machinery of violence; thanks to its peculiar ideology and the role assigned to it in this apparatus of coercion, totalitarianism has discovered a means of dominating and terrorizing human beings from within.
