"A unitary method of thought is indispensable to the interpretation of European history. The pervasive dualisms which distort the thought of western man are an element in this general condition, which therefore must be diagnosed in a language which does not take these dualisms for granted. No interpretation of European man in traditional European terms can bring the truth to light, any more than the color-blind can know their deficiency."

“Did ever the history of the intellect so little conceal so much?”

“Unitary man escapes these confusions through his recognition that one factor is of supreme importance: the maturity proper to man can only come through the experience of adult unity. This experience may come in many ways, but it means that the individual has, for the moment, outgrown the sense of any division, either within himself of from others, through a mature relations to at least one other person. Tension is inherent in the process, but tension does not become frustrating conflict if the overriding unity is realized.”

“The basic challenge to mankind is not population, poverty, war, technology, pollution, religious or racial intolerance, or blind nationalism, but an underlying nihilism promoting violence and frustrating sane policies on these issues. ...the only hope lies in the emergence of a potentially worldwide consensus of heart, mind, and will, appealing to all sane men and women everywhere ...The time has come for the west to speak to the world in universal terms. ...the consensus, if it comes, is likely to surprise by its suddenness, timeliness, and universality.”

“Faced by the dire nihilism of our time, we need a greater honesty... The Western search for unifying truth did not come to an end with Christianity, any more than with the physical theories of forty years ago.”

“Every scientific generation, measured by its most vocal members, exaggerates the historical importance of its own members. ...there is a perpetual temptation to study the latest and to neglect the past.”

“Three centuries of increasingly intense application of the quantitative method had exhausted its guarantee of the progressive improvement of thought, because the regions where the method is adequate have already been explored. It is scarcely possible to avoid the conclusion that a new method is now necessary to supplement the method of quantitative analysis.”
