Since it is always the same person whose mind thinks, wills, and judges, the autonomous nature of these activities has created great difficulties. Reason's inability to move the will, plus the fact that thinking can only "understand” what is past what neither remove it nor "rejuvenate it” ... have led to the various doctrines asserting the mind's impotence and the force of the irrational, in brief to Hume's famous dictum that "Reason is and ought only to be the slave of the passions,” that is, to a rather simple-minded reversal of the Platonic notion of reason's uncontested rulership in the household of the soul. What is so remarkable in all these theories and doctrines is their implicit monism, the claim that behind the obvious multiplicity of the world's appearances and, even more pertinently to our context, behind the obvious plurality of man's faculties and abilities, there must exist a oneness - the old hen pan, "the all is one”.

In the field of non-Euclidean geometry, Riemann... began by calling attention to a distinction that seems obvious once it is pointed out: the distinction between an unbounded straight line and an infinite line. The distinction between unboundedness and infiniteness is readily illustrated. A circle is an unbounded figure in that it never comes to an end, and yet it is of finite length. On the other hand, the usual Euclidean concept of a straight line is also unbounded in that it never reaches an end but is of infinite length.
...he proposed to replace the infiniteness of the Euclidean straight line by the condition that it is merely unbounded. He also proposed to adopt a new parallel axiom... In brief, there are no parallel lines. This ... had been tried... in conjunction with the infiniteness of the straight line and had led to contradictions. However... Riemann found that he could construct another consistent non-Euclidean geometry.

Why should we put up with the present evils in our society? As opposed to the society we are visualizing, the present one can be described as a diseased one. The evils are there on all levels, international and national, and even within the smaller units such as towns and families. Of course, the disease did not appear like a bolt from the blue, either yesterday, or last year. It is the result of factors that have deep roots and long lives. These consist of privations, discriminations oppressions, bigotries, hatreds, and hostilities; poverty, ignorance, hunger, and illiteracy. Each and all of these have been left to us as ar evil heritage from the past. The fundamental difference between our situation today and that of our forefathers is that now knowledge has enabled us to realize that these evils are neither natural nor inevitable in the same way as we have found that cholera or the bubonic plague are not necessary calamities.

Each of our moral, mental, and bodily powers must have its development based upon its own nature, and not based upon artificial and outside influences. Faith must be developed by exercises in believing and cannot be developed from the knowledge and understanding, only, of what is to be believed; thought must grow from thinking, for it cannot come simply from the knowledge and understanding of what is to be thought, or the laws of thought; love must be developed by loving, for it does not arise merely from a knowledge and understanding of what love is and of what ought to be loved; art, also, can only be cultivated through doing artistic work and acquiring skill, for unending discussion of art and skill will not develop them. Such a return to the true method of Nature in the method of the development of our powers necessitates the subordination of education to the knowledge of the various laws which govern those powers.
Johann Heinrich Pestalozzi
Surely one of the reasons for our continued failures throughout these areas [Asia and the Middle East] has been our inability to understand how profound, how irrational, and how erratic has been the reaction generally of the respective peoples to the ideas and impulses that have come to them from the West in recent decades. This applies particularly to the intellectuals who play so prominent a part in political leadership and in the molding of public opinion. To ascertain the reasons for the intensely anti-American attitudes manifested by these people would be to delve deeply into psychological reactions and the origins of various forms of neuroses. I have thoughts about these matters, but will not take up your time with them here.
Only one thing I would emphasize. The respective reactions are obviously emotional and subconscious, and not likely to be altered by any attempts on our part to meet them by any verbal appeal to rational processes.
George F. Kennan
From what can "ought" be derived. The most compelling answer is this: ethics must be somehow based on an appreciation of human nature - on a sense of what a human being is or might be, and on what a human being might want to have or want to be. If that is naturalism, then naturalism is no fallacy. No one could seriously deny that ethics is responsive to such facts about human nature. We may just disagree about where to look for the most compelling facts about human nature -n novels, in religious texts, in psychological experiments, in biological or anthropological investigations. The fallacy is not naturalism but, rather, any simple-minded attempt to rush from facts to values. In other words, the fallacy is greedy reductionism of values to facts, rather than reductionism considered more circumspectly, as the attempt to unify our world-view so that out ethical principles don't clash irrationally with the way the world is.
