Reason is not always reasonable
Reasons aren't really things that make you do other things. Reasons are things that you make up, much later, to reassure everyone that we are all logical and that the world makes sense. We do unreasonable things, because we want to, at the time. No reason. Much later we sit in the wreckage, building reasons out of little bits of wreckage, so we'll have something to show the crash investigators. Look, this is what caused it. So the whole mess at least appears reasonable. So we can convince ourselves that at least there was a reason for the disaster, something we can prevent or avoid, so it'll never happen again. But a lot of the time there's no reason. We just flew it to the ground. Because we felt like it. And we're still dangerous. And it could happen again anytime. Its easier to live with each other afterwards if we give each other reasons.
Metaphysics... is nothing but the inventory of all we possess through pure reason, ordered systematically. Nothing here can escape us, because what reason brings forth entirely out of itself cannot be hidden, but is brought to light by reason itself as soon as reason's common principle has been discovered. The perfect unity of this kind of cognition, and the fact that it arises solely out of pure concepts without any influence that would extend or increase it from experience or even particular intuition, which would lead to a determinate experience, make this unconditioned completeness not only feasible but also necessary. Tecum habita, et noris quam sit tibi curta supellex. Dwell in your own house, and you will know how simple your possessions are. - Persius
Many are destined to reason wrongly others not to reason at all: and others to persecute those who do reason.
You wake up for a reason, you eat for a reason, you dress for a reason and you sleep for a reason. All we do run on the pivot of reasons. For what reasons do you fear? For what reasons do you think? For what reasons do you talk? For what reasons do you open that door each day? For what reasons do you love? For what reasons do you hate? Until we get the reasonable reasons to reason, we shall always ponder over the reasons why we reasoned or we could not reason.
if you give people the reasons to reason and you don't reason, reason!
It is reasonable to reason with God because when you only rely on human reasoning, you will be diverted from your purpose.
Those who invalidate reason, ought seriously to consider, 'whether they argue against reason, with or without reason; if with reason, then they establish the principle, that they are laboring to dethrone;' but if they argue without reason, (which, in order to be consistent with themselves, they must do,) they are out of the reach of rational conviction, nor do they deserve a rational argument.
[At the beginning of modern science], a light dawned on all those who study nature. They comprehended that reason has insight only into what it itself produces according to its own design; that it must take the lead with principles for its judgments according to constant laws and compel nature to answer its questions, rather than letting nature guide its movements by keeping reason, as it were, in leading-strings; for otherwise accidental observations, made according to no previously designed plan, can never connect up into a necessary law, which is yet what reason seeks and requires. Reason, in order to be taught by nature, must approach nature with its principles in one hand, according to which alone the agreement among appearances can count as laws, and, in the other hand, the experiments thought in accordance with these principles - yet in order to be instructed by nature not like a pupil, who has recited to him whatever the teacher wants to say, but like an appointed judge who compels witnesses to answer the questions he puts to them. Thus even physics owes the advantageous revolution in its way of thinking to the inspiration that what reason would not be able to know of itself and has to learn from nature, it has to seek in the latter (though not merely ascribe to it) in accordance with what reason itself puts into nature. This is how natural science was first brought to the secure course of a science after groping about for so many centuries.
...Reason should take on anew the most difficult of all its tasks, namely, that of self-knowledge, and to institute a court of justice, by which reason may secure its rightful claims while dismissing all its groundless pretensions, and this not by mere decrees but according to its own eternal and unchangeable laws; and this court is none other than the critique of pure reason itself.
