The ancients considered mechanics in a twofold respect; as rational, which proceeds accurately by demonstration, and practical. To practical mechanics all the manual arts belong, from which mechanics took its name. But as artificers do not work with perfect accuracy, it comes to pass that mechanics is so distinguished from geometry, that what is perfectly accurate is called geometrical; what is less so is called mechanical. But the errors are not in the art, but in the artificers. He that works with less accuracy is an imperfect mechanic: and if any could work with perfect accuracy, he would be the most perfect mechanic of all; for the description of right lines and circles, upon which geometry is founded, belongs to mechanics. Geometry does not teach us to draw these lines, but requires them to be drawn; for it requires that the learner should first be taught to describe these accurately, before he enters upon geometry; then it shows how by these operations problems may be solved.

It would be difficult to describe the subtle brotherhood of men that was here established on the seas. No one said that it was so. No one mentioned it. But it dwelt in the boat, and each man felt it warm him. They were a captain, an oiler, a cook, and a correspondent, and they were friends, friends in a more curiously iron-bound degree than may be common. The hurt captain, lying against the water-jar in the bow, spoke always in a low voice and calmly, but he could never command a more ready and swiftly obedient crew than the motley three of the dingey. It was more than a mere recognition of what was best for the common safety. There was surely in it a quality that was personal and heartfelt. And after this devotion to the commander of the boat there was this comradeship that the correspondent, for instance, who had been taught to be cynical of men, knew even at the time was the best experience of his life. But no one said that it was so. No one mentioned it.

If dialectical logic understands contradiction as "necessity” belonging to the very "nature of thought,” ... it does so because contradiction belongs to the very nature of the object of thought, to reality, where Reason is still Unreason, and the irrational still the rational. Conversely, all established reality militates against the logic of contradictions - it favors the modes of thought which sustain the established forms of life and the modes of behavior which reproduce and improve them. The given reality has its own logic and its own truth; the effort to comprehend them as such and to transcend them presupposes a different logic, a contradicting truth. They belong to modes of thought which are non-operational in their very structure; they are alien to scientific as well as common-sense operationalism. ... These modes of thought appear to be a relic of the past, like all non-scientific and non-empirical philosophy. They recede before a more effective theory and practice of Reason.

What were they saying?” Daly asked.
"They disapprove of your profession,” Doro told him.
"Heathen savages,” Daly muttered. "They're like animals. They're all cannibals.”
"These aren't,” Doro said, "though some of the their neighbors are.”
"All of them,” Daly insisted. "Just give them the chance.”
Doro smiled. "Well, no doubt the missionaries will reach them eventually and teach them to practice only symbolic cannibalism.”
Daly jumped. He considered himself a pious man in spite of his work. "You shouldn't say such things,” he whispered. "Not even you are beyond the reach of God.”
"Spare me your mythology,” Doro said, "and your righteous indignation.” Daly had been Doro's man too long to be pampered in such matters. "At least we cannibals are honest about what we do,” Doro continued. "We don't pretend as your slavers do to be acting for the benefit of our victims' souls. We don't tell ourselves we've caught them to teach them civilized religion.

In the winter of 1841 Schelling gave his famous series of lectures at the University of Berlin before a distinguished audience including Kierkegaard, Burckhardt, Engels, Bakunin. Schelling set out to overthrow Hegel, whose vast rationalist system including the identification of abstract truth with reality and the bringing of all history into an "absolute whole,” held immense and dominant popularity in the Europe of the middle of the nineteenth century. – 1844 Kierkegaard published Philosophical Fragments, and two years later he wrote the declaration of independence for existentialism, Concluding Unscientific Postscript to Philosophical Fragments. Also in 1844 there appeared the second edition of Schopenhauer's The world as will and idea,.. central emphasis "will” along with "idea” -- two related works by Marx 1844-45 – "attacked abstract truth' as "ideology” "using Hegel as his whipping boy” "men and groups bring truth into being” "money economy turns people into things”.

In the last centuries of the empire, educational standards and literacy had fallen. In the dulled heads of the masses, distracted by cheap food and the barbaric spectacles of the coliseums, the values on which Rome had been founded and the ancient rationalism of the Greeks had been replaced by mysticism and superstition. It was-Honorius had explained to his pupil-as if a whole culture was losing its mind. People were forgetting how to think, and soon they would forget they had forgotten. And, to Honorius's thinking, Christianity only exacerbated that problem.
"You know, Augustine warned us that belief in the old myths was fading-even a century and a half ago, as the dogma of the Christians took root. And with the loss of the myths, so vanishes the learning of a thousand years, which are codified in those myths, and the monolithic dogmas of the Church will snuff out rational inquiry for ten more centuries. The light is fading, Athalric.”.
