Here are 3 different versions, which I've learned usually indicates some paraphrasing is going on here [or variations in translation].
I see your quote attributed to Aristotlehttp://setiathome.ssl.berkeley.edu/fcgi-bin/fcgi?cmd=view_feedback&id=14396
An alteration of the condition of the soul produces a change in the shape of the body and vice versa, an altered shape of the body leads to a changed condition in the souls.
~ Aristotle [“Found without reference”]http://www.ancient-egypt.de/html/lines_of_tension.html
"Mind and body I suggest react sympathetically to each other. A change in the state of the mind, a change in the state of the body, conversely a change in the shape of the body a change in the state of the mind.”
~ Aristotle “wrote”http://www.alantyedesign.ndirect.co.uk/quest2.htm
"Soul and body 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."
~ Aristotle http://home.earthlink.net/~kmcguire2003/about.htm
If I was going to spend any time researching this, I would probably start with looking at
Aristotle’s Nichomachean Ethics
Books 1 - 10http://www.constitution.org/ari/ethic_00.htm
A couple misc. quotes:
‘One should not ask if the soul and the body are one, any more than one should ask it of the wax and the shape, or in general of the matter of anything and that of which it is the matter.’
~ Aristotle, cited in A Brief Guide to Ideas
, William Raeper, Linda Edwardshttp://www.zondervanchurchsource.com/product.asp?ISBN=0310227747
“We must maintain, further, that the soul is also the cause of the living body as the original source of local movement. The power of locomotion is not found, however, in all living things. But change of quality and change of quantity are also due to the soul. Sensation is held to be a qualitative alteration, and nothing except what has soul in it is capable of sensation. The same holds of the quantitative changes which constitute growth and decay; nothing grows or decays naturally except what feeds itself, and nothing feeds itself except what has a share of soul in it.”
~ Aristotle, as cited by A. L. Davidson
In general, Plato
contends that the soul is distinct from the body and is capable of maintaining a separate existence from it. Aristotle
, in contrast, feels that body and soul are two aspects of the same underlying substance (form and matter). http://www.religiousstudies.co.uk/pdf/mindbodysoul.pdf
