Lewis S. Feuer shows that the gestation of the hypotheses of original-minded scientists, such as Darwin, Einstein, or Bohr, is in large part a subconscious process. Scientists try to project upon the world structural laws that, beside fitting the given physical realities, will also realize their own emotional longings among alternative worldviews. Repeatedly, too, in examining the standpoints of philosophical figures ranging from Spinoza, Descartes, Kant, and Mill to contemporary figures such as Einstein, Lovejoy, and Hook, Feuer illumines how sociological antipathies project themselves into scientific divergences. Feuer delves into the bearing of emotive beliefs such as pacifism, socialism, anti-Semitism, upon the formation of concurrent worldviews, often fixations of scientific belief, held with the same passion in science as in religion.

Kant's Observations of 1764 and Remarks of 1764-5 (a set of fragments written in the margins of his copy of the Observations) document a crucial turning point in his life and thought. Both reveal the growing importance for him of ethics, anthropology and politics, but with an important difference. The Observations attempts to observe human nature directly. The Remarks, by contrast, reveals a revolution in Kant's thinking, largely inspired by Rousseau, who 'turned him around' by disclosing to Kant the idea of a 'state of freedom' (modelled on the state of nature) as a touchstone for his thinking. This and related thoughts anticipate such famous later doctrines as the categorical imperative. This collection of essays by leading Kant scholars illuminates the many and varied topics within these two rich works, including the emerging relations between theory and practice, ethics and anthropology, men and women, philosophy, history and the 'rights of man'.

By controversially turning away from the current debates which surround social theory, this book provides an historical analysis of the profound burden of sociology and its implications today.

If Kant had never made the "critical turn" of 1773, would he be worth more than a paragraph in the history of philosophy? Most scholars think not. But this text challenges that view by revealing a precritical Kant who was immensely more influential than the one philosophers think they know.

This highly readable volume offers a broad introduction to modern philosophy and philosophers. Scharfstein contends that personal experience, especially that of childhood, affects philosophers' sense of reality and hence the content of their philosophies. Basing his argument on biographical studies of twenty great philosophers, from Descartes to Sartre, he provides the beginnings of a psychological history of philosophy.
