Are There Any Philosophies of the Human Body? There is so much out there about the body if you're willing to look for it! The most obvious place to look is Merleau-Ponty's
Phenomenology of Perception, which gives primacy to the body in a way that we still have yet to appreciate. If you're interested in sociological aspects of the body - which any good philosopher ought to be - Chris Shilling's
The Body and Social Theory is a classic that covers some of the most important theorizing on the body in contemporary research (I just saw that he also recently wrote one of those 'Very Short Introduction' guides to the body, which might be a useful first foray into theories of the body).
The body also figures massively in feminist, disability, and race studies, many of which, by bringing out the specificity of gendered, racialized, and disabled bodies, aim to contest the implicit universality of alot of prior philosophical work (see, as exemplary instances of each: Iris Marion Young -
Throwing Like a Girl; Franz Fanon -
Black Skin, White Masks; Tom Shakespeare -
Disability Rights and Wrongs).
And of course the body plays a massive role in understandings of cognition more generally (as pointed out by
@Pfhorrest), where you can look to works like George Lakoff and Mark Johnston's
Philosophy in the Flesh, Evan Thompson's
Mind In Life, or one of my favourites, Maxine Sheets-Johnston's
The Primacy of Movement. Alot of contemporary Spinozist's have also placed a great deal of focus on the body and it's role in thinking ethics - an example here being something like Heidi Ravven's
The Self Beyond Itself.
This is all just a tiny, tiny snippet of philosophical work that focuses on the body, and there's heaps to look into if you're interested.
