“Tis impossible to judge with much Precision of the true Motives and Qualities of human Actions, or of the Propriety of Rules contrived to govern them, without considering with like Attention, all the Passions, Appetites, Affections in Nature from which they flow. An intimate Knowledge therefore of the intellectual and moral World is the sole foundation on which a stable structure of Knowledge can be erected.”

“The ruling British elite are like animals--not only in their morality, but in their outlook on knowledge. They are clever animals, who are masters of the wicked nature of their own species, and recognize ferally the distinctions of the hated human species. Nonetheless, obsessively dedicated to being such animals, they can not [sic] assimilate those qualities unique to true human beings.”

“The historian is not only a lover of truth, not only a chronicler of events. These, indeed, he must be at his peril, but how much more! Insight into human nature—and this implies the rarest knowledge and finest sympathy of which man is capable; the power of tracing the delicate relation between deed and motive, and the pressure of action upon circumstance and circumstance upon action; knowledge of the world, in short, in the highest sense of that expression.”

“This education, therefore, results at the very outset in knowledge which transcends all experience, which is abstract, absolute, and strictly universal, and which includes within itself beforehand all subsequently possible experience. On the other hand, the old education was concerned, as a rule, only with the actual qualities of things as they are and as they should be believed and rioted, without anyone being able to assign a reason for them. It aimed, therefore, at purely passive reception by means of the power of memory, which was completely at the service of things. It was, therefore, impossible to have any idea of the mind as an independent original principle of things themselves.”

“The prejudices of the second species, since they impose upon the intellect by the sensual conditions restricting the mind if it wishes in certain cases to attain to what is intellectual, lurk more deeply. One of them is that which affects knowledge of quantity, the other that affecting knowledge of qualities generally. The former is: every actual multiplicity can be given numerically, and hence, every infinite quantity; the latter, whatever is impossible contradicts itself. In either of them the concept of time, it is true, does not enter into the very notion of the predicate, nor is it attributed as a qualification to the subject. But yet it serves as a means for forming an idea of the predicate, and thus, being a condition, affects the intellectual concept of the subject to the extent that the latter is only attained by its aid.”

“Philosophy can never reconcile itself with science. Science aims at self-evident truths and finds in them that "natural necessity" which, after having proclaimed itself for ever eternal, claims to serve as the foundation of all knowledge and strives to rule over all wanton "suddenly."”

Lev Shestov (1866–1938) Russian theologian

But philosophy has always been, and will always be, a fight with and a conquest of self-evident truths; philosophy is not looking for any "natural necessity", it sees in naturalness and in necessity alike an evil magic, which, if one cannot quite shake it off (for in this no mortal has ever yet succeeded), yet one must at least call by its right name; and even this is an important step! p. 342
