He states, 'there is no definite concept of the body. Rather, there is a material world, the properties of which are to be discovered, with no a priori demarcation of what will count as "body". The mind-body problem can therefore not be formulated. The problem cannot be solved, because there is no clear way to state it. Unless someone proposes a definite concept of the body, we cannot ask whether some phenomena exceed its bounds. Similarly, we cannot pose the problem of other minds'.
A body (in the physical sense of the term) is
a spatially or spatiotemporally extended material object or substance. A body is
three-dimensional or
four-dimensional, depending on whether or not it has temporal parts in addition to its spatial parts; but it cannot be
zero-dimensional, such that if elementary particles were literally like mathematical
points, they wouldn't be bodies.
Here are traditional definitions:

"The word
body, in the most general acceptation, signifieth that which filleth, or occupieth some certain room, or imagined place; and dependeth not on the imagination, but is a real part of that we call the
universe."
(Hobbes, Thomas.
Leviathan. 1651. Oxford: Oxford University Press, 1998. [Pt. 3, ch. 34, §2.] p. 261)
"We now understand the nature of imaginary space, in which we suppose nothing external to exist, but only the pure absence of the things which, when they existed, left their images in the mind. Let us next suppose that one of these things is put back again, or re-created. It is therefore necessary for that re-created or replaced thing not only to occupy some part of the said space (i.e. to coincide and be coextensive with it), but also to be something which does not depend on our imagination. But this is the very thing which is customarily called
body on account of its extension;
self-subsistent on account of its independence from our thought;
existent because it subsists outside us; and finally
substance or
subject because it seems to support and underlie imaginary space, so that it is not by the senses, but only by reason that we understand that something is there. So the definition of body is something like this:
Body is whatever coincides or is coextensive with a part of space, and does not depend on our thought."
(Hobbes, Thomas.
Elementorum philosophiae, sectio prima: De corpore (1655, engl. 1656), Part II, Ch. 8: Body and Accident, 8.1 The Definition of "Body")
"A body, in the physical sense, is
a matter between determinate boundaries (which therefore has a figure). The space between these boundaries, considered in accordance with its magnitude, is the volume [of the body]."
(Kant, Immanuel.
Metaphysical Foundations of Natural Science. 1786. Translated and edited by Michael Friedman. Cambridge: Cambridge University Press, 2004. p. 64)
"…to be body, that is to say, to be formed and specifically determined matter…"
(Schopenhauer, Arthur.
Parerga and Paralipomena, Vol. 2. Translated by E. F. J. Payne. Oxford: Oxford University Press, 1974. p. 107)
