Soul and body,

I suggest,

react

sympathetically

upon each other;

a change

in the state of the

soul produces

a change

in the shape

of the body,

and conversely:

a change in the

shape of the body

produces

a change in

the state of the soul.

Surprise!

Aristotle,

Physiognomics, c.350 B.C.E.

Aristotle’s theory is

much quoted today.

It is humbling

to think

that the

ancient Greeks

framed questions

that still preoccupy us

more than 23 centuries later.

It is exciting too,

because over the

past two decades,

scientists

have acquired

powerful

new imaging tools

that are

revolutionizing

our understanding

of the connection

between

body and mind.
