Explanations are clear but since no one to whom a thing is explained can connect the explanations with what is really clear, therefore clear explanations are not clear. Now this is a simple thing that anybody who has ever argued or quarreled knows perfectly well is a simple thing, only when they read it they do not understand it because they do not see that understanding and believing are not the same thing.

Sing the melody line you hear in your own head. Remember, you don't owe anybody any explanations, you don't owe your parents any explanations, you don't owe your professors any explanations.
Bono
These rules will enable you to have a free and sound judgment; since good judgment is born of clear understanding, and a clear understanding comes of reasons derived from sound rules, and sound rules are the issue of sound experience — the common mother of all the sciences and arts. Hence, bearing in mind the precepts of my rules, you will be able, merely by your amended judgment, to criticise and recognise every thing that is out of proportion in a work, whether in the perspective or in the figures or any thing else.
Leonardo da Vinci
...when we wish to demonstrate a general theorem, we must give the rule as applied to a particular case; but if we wish to demonstrate a particular case, we must begin with the general rule. For we always find the thing obscure which we wish to prove, and that clear which we use for the proof; for, when a thing is put forward to be proved, we first fill ourselves with the imagination that it is therefore obscure, and on the contrary that what is to prove it, is clear, and so we understand it easily. 40
Blaise Pascal
Kuhn's theory suffers from a fatal flaw. It explains the succession from one paradigm to another in sociological or psychological terms, rather than as having primarily to do with the objective merit of the rival explanations. Yet unless one understands science as a quest for explanations, the fact that it does find successive explanations, each objectively better than the last, is inexplicable. (Ch. 13)
David Deutsch
It is clear that there is no classification of the Universe that is not arbitrary and full of conjectures. The reason for this is very simple: we do not know what kind of thing the universe is.
