Proprioception, Mind, Body

Proprioception is the awareness of one's Motility.  It is also known as Kinesthesia, and is sometimes characterized as the 'sixth sense'.  Of scholarly significance in the latter case is that it thus constitutes a kind of Sense-Experience that is outside of the range of standard Empiricism, but of any concept of Experience that begins either with a sedentary scenario, or one that abstracts from the Body from the outset.  Hence, Proprioception is unknown in the main systems of Modern Philosophy, and their descendants.  The one exception, of course, is Spinoza's doctrine, according to which Mind is the Idea of the Body, a concept perhaps influenced by concepts of Proprioception that precede the Ethics. Spinoza does not develop it as such, but entailed in the concept of Proprioception is the concept of the activity of the standard five Senses as fundamentally motor, i. e. as grounded in the active exercise of Sense-Organs--looking at, listening to, touching, tasting, and, smelling.  The very possibility of this concept of Sense-activity exposes the arbitrary abstraction from Motility of the standard accounts, an abstraction likely rooted in an effort to separate Mind and Knowledge from Corporeality.
