Gustav Theodor Fechner (1801-1887) was a German physicist, psychologist, and philosopher, best known to historians of science as the founder of psychophysics, the experimental study of the relation between mental and physical processes. Michael Heidelberger's exhaustive exploration of Fechner's writings, in relation to current issues in the field, successfully reestablishes Fechner's place in the history and philosophy of science.

An argument against neobehaviorism and for "naturalized Cartesianism," which couples a wholly materialist approach to the mind with a fully realist attitude to the phenomena of conscious experience. In Mental Reality, Galen Strawson argues that much contemporary philosophy of mind gives undue primacy of place to publicly observable phenomena, nonmental phenomena, and behavioral phenomena (understood as publicly observable phenomena) in its account of the nature of mind. It does so at the expense of the phenomena of conscious experience. Strawson describes an alternative position, "naturalized Cartesianism," which couples the materialist view that mind is entirely natural and wholly physical with a fully realist account of the nature of conscious experience. Naturalized Cartesianism is an adductive (as opposed to reductive) form of materialism. Adductive materialists don't claim that conscious experience is anything less than we ordinarily conceive it to be, in being wholly physical. They claim instead that the physical is something more than we ordinarily conceive it to be, given that many of the wholly physical goings on in the brain constitute—literally are—conscious experiences as we ordinarily conceive them. Since naturalized Cartesianism downgrades the place of reference to nonmental and publicly observable phenomena in an adequate account of mental phenomena, Strawson considers in detail the question of what part such reference still has to play. He argues that it is a mistake to think that all behavioral phenomena are publicly observable phenomena.This revised and expanded edition of Mental Reality includes a new appendix, which thoroughly revises the account of intentionality given in chapter 7.

The first half of this book argues that physicalism cannot account for consciousness, and hence cannot be true. The second half explores and defends Russellian monism, a radical alternative to both physicalism and dualism. The view that emerges combines panpsychism with the view that the universe as a whole is fundamental.

The first complete translation into English of this Tibetan text, together with the informative commentary by the 8th century master Buddhaguhya. This text is of seminal importance for the history of Buddhist Tantra, especially as very little has been published concerning the origins of Tantra in India.
