Immanuel Kant on Space and Time

In his Inaugural Dissertation of 1770, Immanuel Kant denies the reality of time and space and of temporal and spatial form. He writes:

"Time is not something objective and real, neither a substance, nor an accident, nor a relation. It is the subjective condition necessary by the nature of the human mind for coordinating any sensible objects among themselves by a certain law; time is a pure intuition.

"Space is not something objective and real, neither substance, nor accident, nor relation; but subjective and ideal, arising by fixed law from the nature of the mind like an outline for the mutual co-ordination of all external sensations whatsoever."

Kant is not implying that the existence of objects perceived in space and time is dependent on the nature of the human mind; rather, he is saying that the existence of mind-dependent forms like time and space make it possible for the human mind to precisely observe the mind-independent objects.

Of Experience by Michel de Montaigne

Michel de Montaigne, in his final essay, “Of Experience,” (The Essays of Michel de Montaigne; Chapter 13), talks about his lifelong quest for self knowledge through life’s experiences. He begins his essay with these lines: “There is no desire more natural than that of knowledge. We try all ways that can lead us to it; where reason is wanting, we therein employ experience.”

In the last paragraph of the essay, he writes:
The pretty inscription wherewith the Athenians honoured the entry of Pompey into their city is conformable to my sense: “By so much thou art a god, as thou confessest thee a man.” ’Tis an absolute and, as it were, a divine perfection, for a man to know how loyally to enjoy his being. We seek other conditions, by reason we do not understand the use of our own; and go out of ourselves, because we know not how there to reside. ’Tis to much purpose to go upon stilts, for, when upon stilts, we must yet walk with our legs; and when seated upon the most elevated throne in the world, we are but seated upon our breech. The fairest lives, in my opinion, are those which regularly accommodate themselves to the common and human model without miracle, without extravagance. Old age stands a little in need of a more gentle treatment. 
What he is essentially saying in the above paragraph is that no matter that we may mount on stilts, we still must walk on our own legs; and on the highest throne in the world, we still sit only on our own bottom.

Aristotle on Who Should Be The Judge

In Metaphysics, Aristotle summarizes the arguments from his skeptic opponents in a paragraph: "There are, both among those who have these convictions and among those who merely profess these views, some who raise a difficulty by asking, who is to be the judge of the healthy man, and in general who is likely to judge rightly on each class of questions. But such inquiries are like puzzling over the question whether we are now asleep or awake. And all such questions have the same meaning. These people demand that a reason shall be given for everything; for they seek a starting-point, and they seek to get this by demonstration, while it is obvious from their actions that they have no conviction. But their mistake is what we have stated it to be; they seek a reason for things for which no reason can be given; for the starting-point of demonstration is not demonstration."
