In
Mind & Cosmos (pp. 86-7) Nagel writes:
"I explored the possibility of a reductive account of consciousness, based on some form of universal monism or panpsychism." As far as I can tell, he doesn't (explicitly) say that it is true.
anonymous66 wrote: ↑July 12th, 2018, 8:49 amNagel argues that the nature of our world is such that it follows that physicalism is false. Here it gets confusing, because Nagel assumes that physicalism and panpsychism are mutually exclusive- he disagrees with Strawson on that point.
Anyway, Nagel also points out that in the past, both theists and physicalists believed that there were only the 2 options.
Nagel is suggesting a third option: Panpsychism. Again, you have to remember that Nagel believes that physicalism and panpsychism are mutually exclusive.
I guess you could say that if Galen Strawson is correct, then it could be the case that the 3rd option is a physicalism that is consistent with panpsychism.
Whether it is depends on what physicalism is and what panpsychism is.
Strawson's concept of physicality has been criticized for being so underspecified that it is vacuous. If "physical" is just a natural-kind term, with "physical world" meaning nothing more than "concrete/spatiotemporal world", then the real essence of the physical might turn out to be mental, in which case even idealism could count as a version of physicalism. But this is absurd!
As long as all mental properties are physical ones, the view that
all physical objects have mental properties is logically compatible with physicalism.
However, the prefix "pan-" is often not taken literally, with panpsychism being defined more narrowly as the view that all or at least some kinds of
basic/fundamental physical objects have mental/experiential properties. If those physical objects are mereological atoms, i.e. lack proper parts, then their mental/experiential properties are neither reducible to nor emergent from structural physical properties of them, since the having of structural properties presupposes mereological complexity, i.e. the having of proper parts which have properties of their own, and between which relations obtain.
Therefore, panpsychism thus defined is ontologically incompatible with physicalism, because the mental/properties (of basic, mereologically atomic physical objects) postulated by the former are
hyperphysical in the sense of being
neither reducible to nor emergent from structural physical properties.
By the way, Nagel writes that…
"Materialism requires reductionism; therefore the failure of reductionism requires an alternative to materialism."
(Nagel, Thomas.
Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly False. New York: Oxford University Press, 2012. p. 15)
There are quite a few philosophers who deny that "materialism requires reductionism", because they think that it requires reductionism
or emergentism. They argue that "the failure of reductionism" doesn't require "an alternative to materialism" but an alternative to
reductive materialism; and with emergentive materialism being a genuine version of materialism, there is a
materialistic alternative to reductive materialism.
Anyway, "Physicalistic neuroscience has not yet succeeded in reductively explaining subjective experience" is not synonymous with "Physicalistic neuroscience has failed in reductively explaining subjective experience". Nobody can predict the progress and future success of (neuro)science!

Yes, but what he offers is nothing more than hand-waving. He doesn't even offer a sketch of a teleological theory of natural evolution that deserves to be taken seriously by the scientists.
By the way, there is no logical inconsistency between physicalism and the postulation of teleological factors in nature. However, there's a distinction between
physioteleological factors and
psychoteleological ones (describable in terms of intentional mental states, especially of personal agents such as God); and physicalism is arguably incompatible with the view that cosmic and biological evolution has always been influenced by psychoteleological factors. (Colin Allen calls this view "teleomentalism":
"Teleomentalists regard the teleology of psychological intentions, goals, and purposes as the primary model for understanding teleology in biology." –
Teleological Notions in Biology)
"As various sorts of mentalism can be thoroughly mechanistic, so conversely a materialism is compatible with any amount of vital spontaneity, from the palest tychism, through diverse shades of organicism, to the rosiest teleology."
