eme than the other. The good
is the beautiful, and the beautiful is the symmetrical, and there is no
greater or fairer symmetry than that of body and soul, as the contrary
is the greatest of deformities. A leg or an arm too long or too short
is at once ugly and unserviceable, and the same is true if body and soul
are disproportionate. For a strong and impassioned soul may 'fret the
pigmy body to decay,' and so produce convulsions and other evils. The
violence of controversy, or the earnestness of enquiry, will often
generate inflammations and rheums which are not understood, or assigned
to their true cause by the professors of medicine. And in like manner
the body may be too much for the soul, darkening the reason, and
quickening the animal desires. The only security is to preserve the
balance of the two, and to this end the mathematician or philosopher
must practise gymnastics, and the gymnast must cultivate music. The
parts of the body too must be treated in the same way--they should
receive their appropriate exercise. For the body is set in motion when
it is heated and cooled by the elements which enter in, or is dried up
and moistened by external things; and, if given up to these processes
when at rest, it is liable to destruction. But the natural motion, as
in the world, so also in the human frame, produces harmony and divides
hostile powers. The best exercise is the spontaneous motion of the body,
as in gymnastics, because most akin to the motion of mind; not so
good is the motion of which the source is in another, as in sailing or
riding; least good when the body is at rest and the motion is in parts
only, which is a species of motion imparted by physic. This should only
be resorted to by men of sense in extreme cases; lesser diseases are
not to be irritated by medicine. For every disease is akin to the living
being and has an appointed term, just as life has, which depends on the
form of the triangles, and cannot be protracted when they are worn out.
And he who, instead of accepting his destiny, endeavours to prolong
his life by medicine, is likely to multiply and magnify his diseases.
Regimen and not medicine is the true cure, when a man has time at his
disposal.

Enough of the nature of man and of the body, and of training and
education. The subject is a great one and cannot be adequately treated
as an appendage to another. To sum up all in a word: there are three
kinds of soul located within us, and any one o
