David Galin, among other researchers, has pointed out that teachers have three main tasks: first, to train both hemispheres - not only the verbal, symbolic, logical left hemisphere, which has always been trained in the traditional education, but also the relational, holistic right hemisphere, which is largely neglected in today's schools; second, to train students to use the cognitive style suited to the tasks at hand; and third, to train students to be able to bring both styles - both hemispheres - to bear on a problem in an integrated manner.
When teachers can pair the complementary modes or fit one mode to the appropriate task, teaching and learning will become a much more precise process. Ultimately, the goal will be to develop both halves of the brain. Both modes are necessary for full human functioning and both are necessary for creative work of all kinds, whether writing or painting, developing a new theory in physics, or dealing with environmental problems.

Poor Joshua! Victim of repeated attacks by an irresponsible, bullying, cowardly, and intemperate father, and abandoned by respondents who placed him in a dangerous predicament and who knew or learned what was going on, and yet did essentially nothing except, as the Court revealingly observes, ante, at 193, "dutifully recorded these incidents in [their] files." It is a sad commentary upon American life, and constitutional principles - so full of late of patriotic fervor and proud proclamations about "liberty and justice for all" - that this child, Joshua DeShaney, now is assigned to live out the remainder of his life profoundly retarded. Joshua and his mother, as petitioners here, deserve - but now are denied by this Court - the opportunity to have the facts of their case considered in the light of the constitutional protection that 42 U.S.C. 1983 is meant to provide."

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.

Third Theory.-According to this theory, there is nothing in the whole Universe... that is due to chance; everything is the result of will, intention, and rule. It is a matter of course that he who rules must know. The Mohametan Ashariyah adhere to this theory, notwithstanding evident absurdities implied in it. ...The Ashariyah were therefore compelled to assume that motion and rest of living beings are predestined, and that it is not in the power of a man to do a certain thing or to leave it undone. ...It follows also from this theory, that precepts are perfectly useless, since the people to whom any law is given... can neither do what they are commanded nor abstain from what they are forbidden. ...According to this theory, it must also be assumed that the actions of God have no final cause. All these absurdities are admitted by the Ashariyah for the purpose of saving this theory.

The social sciences building at the University of Chicago indeed still bears since it was built 40 years ago on its outside an inscription taken from the famous physicist Lord Kelvin: "When you cannot measure, your knowledge is meager and unsatisfactory." I will admit that that may be true, but it is certainly not scientific to insist on measurement where you don't know what your measurements mean. There are cases where measurements are not relevant. What has done much damage to microeconomics is striving for a pseudo-exactness by imitating methods of the physical sciences which have to deal with what are fundamentally much more simple phenomena. And the assumption that it is possible to ascertain all the relevant particular facts still completely dominates the alternative methods of dealing with our constitutional ignorance, which economists have tried to overcome. This of course, is what has come to be called macroeconomics as distinct from microeconomics.
