You have probably heard the saying, "You are what you eat."
In one sense, that saying is obviously false; you could not really
become a chocolate-chip cookie no matter how many of them you eat.
But in another sense, the saying is obviously true; your body can
only make cells from the raw materials it is provided. It is now
well established, for example, that malnutrition in childhood has
devastating effects on the development of the brain. The saying is
also true in yet another sense; the body must somehow dispose of
everything it is fed. Whether it be a toxic substance such as
alcohol or an excess of a nutrient such as sugar, your body somehow
processes whatever you eat (or drink).
Even more than the body is what you eat, îthe mind is what you
learnī. A classic view is that a mind begins life as a tabula rasa
(a clean slate). A more contemporary view is that the mind begins
with a number of pre-dispositions to develop in one way or another
but even according to this view, the mind is primarily a result of
the experiences the person has.
In contrast to the hard mental effort required to learn the
kind of verbal material covered in college courses, other forms of
learning are remarkably rapid and durable. Acquiring an emotional
reaction of liking or disliking something can happen from a single
experience. In such cases, learning results from mere exposure to
the situation. Which is more, the experience does not have to be
real. Beginning very early in life, we humans acquire most of our
attitudes, beliefs, values, styles, and dispositions vicariously,
from observation of others. Some psychologists think imitation is
an innate human tendency; others contend that it is learned. Both
agree, however, that a large part of socialization is derived from
observational learning (imitation).
This means that your mind is whatever is has been "fed" in the
past, and it will become whatever you feed it in the future. You
feed your mind by the kind of books you read, as well as the kind
of music you listen to and TV you watch. There is simply no doubt
that exposure to sex/drugs/violence begets sex/drugs/violence. It
equally follows that exposure to love/health/benevolence begets
those qualities. Some people conclude from this fact that socially
undesirable activities should be banned from the public media. My
own belief is that attempts to proscribe behavior will not work in
modern society, and that knowledge is a much more powerful weapon
than rules and regulations.
Accordingly, it is your choice whether or not to consume junk
foods and obscene publications. It is not so much an occasional
bite as your regular diet that determines who and what you are.
