“For the classics philosophical insight was the product of a life of leisure; for me a life of leisure is the product of philosophical insight.”

Context: No longer did philosophers aspire to the deep spiritual insights and broad moral vision of Socrates, Plato, and Aristotle. They divided into conflicting schools and wandered through the Greco-Roman world as permanent immigrants, picking up tutoring jobs as they could.... the upshot was a debased intellectual climate, fragmented and agnostic.

"The Way Of Chuang Tzu".
The Way of Chuang-Tzŭ (1965)
Context: The humor, the sophistication, the literary genius, and philosophical insight of Chuang Tzu are evident to anyone who samples his work. But before one can begin to understand even a little of his subtlety, one must situate him in his cul­tural and historical context. That is to say that one must see him against the background of the Confucianism which he did not hesitate to ridicule, along with all the other sedate and accepted schools of Chinese thought, from that of Mo Ti to that of Chuang's contemporary, friend, and constant op­ponent, the logician Hui Tzu. One must also see him in rela­tion to what followed him, because it would be a great mistake to confuse the Taoism of Chuang Tzu with the popular, de­ generate amalgam of superstition, alchemy, magic, and health­ culture which Taoism later became.
The true inheritors of the thought and spirit of Chuang Tzu are the Chinese Zen Buddhists of the Tang period (7th to 10th centuries A. D.). But Chuang Tzu continued to exert an influence on all cultured Chinese thought, since he never ceased to be recognized as one of the great writers and think­ ers of the classical period. The subtle, sophisticated, mystical Taoism of Chuang Tzu and Lao Tzu has left a permanent mark on all Chinese culture and on the Chinese character itself. There have never been lacking authorities like Daisetz T. Suzuki, the Japanese Zen scholar, who declare Chuang Tzu to be the very greatest of the Chinese philosophers. There is no question that the kind of thought and culture represented by Chuang Tzu was what transformed highly speculative Indian Buddhism into the humorous, iconoclastic, and totally practical kind of Buddhism that was to flourish in China and in Japan in the various schools of Zen. Zen throws light on Chuang Tzu, and Chuang Tzu throws light on Zen.

Tools of Critical Thinking: Metathoughts for Psychology (1997)

Incommensurables donc, mais aussi inséparables. Pas de discours qui mérite d’être appelé philosophique, s’il est séparé de la vie philosophique, pas de vie philosophique, si elle n’est étroitement liée au discours philosophique. C’est là d’ailleurs que réside le danger inhérent à la vie philosophique: l’ambiguïté du discours philosophique.

Human Nature and Social Theory (1969)
Context: What about the utopian thinkers of all ages, from the Prophets who had a vision of eternal peace, on through the Utopians of the Renaissance, etc.? Were they just dreamers? Or were they so deeply aware of new possibilities, of the changeability of social conditions, that they could visualize an entirely new form of social existence even though these new forms, as such, were not even potentially given in their own society? It is true that Marx wrote a great deal against utopian socialism, and so the term has a bad odor for many Marxists. But he is polemical against certain socialist schools which were, indeed, inferior to his system because of their lack of realism. In fact, I would say the less realistic basis for a vision of the uncrippled man and of a free society there is, the more is Utopia the only legitimate form of expressing hope. But they are not trans-historical as, for instance, is the Christian idea of the Last Judgment, etc. They are historical, but the product of rational imagination, rooted in an experience of what man is capable of and in a clear insight into the transitory character of previous and existing society.

Myth of Megalopolis <!-- p. 545 -->
The City in History (1961)
Context: Unfortunately, once an economy is geared to expansion, the means rapidly turn into an end and "the going becomes the goal." Even more unfortunately, the industries that are favored by such expansion must, to maintain their output, be devoted to goods that are readily consumable either by their nature, or because they are so shoddily fabricated that they must soon be replaced. By fashion and built-in obsolescence the economies of machine production, instead of producing leisure and durable wealth, are duly cancelled out by the mandatory consumption on an even larger scale.
