Sensation, then, is confined to the simple or homogeneous parts.
But, as might reasonably be expected, the organ of touch, though still
homogeneous, is yet the least simple of all the sense-organs. For
touch more than any other sense appears to be correlated to several
distinct kinds of objects, and to recognize more than one category
of contrasts, heat and cold, for instance, solidity and fluidity,
and other similar oppositions. Accordingly, the organ which deals with
these varied objects is of all the sense-organs the most corporeal,
being either the flesh, or the substance which in some animals takes
the place of flesh.
Now as there cannot possibly be an animal without sensation, it
follows as a necessary consequence that every animal must have some
homogeneous parts; for these alone are capable of sensation, the
heterogeneous parts serving for the active functions. Again, as the
sensory faculty, the motor faculty, and the nutritive faculty are
all lodged in one and the same part of the body, as was stated in a
former treatise, it is necessary that the part which is the primary
seat of these principles shall on the one hand, in its character of
general sensory recipient, be one of the simple parts; and on the
other hand shall, in its motor and active character, be one of the
heterogeneous parts. For this reason it is the heart which in
sanguineous animals constitutes this central part, and in bloodless
animals it is that which takes the place of a heart
