I. _All human achievement comes about through some form of bodily
activity._

II. _All bodily activity is caused, controlled and directed by the
mind._

III. _The mind is the instrument you must employ for the
accomplishment of any purpose._

[Sidenote: _The Two Types of Thought_]

You have learned that the fundamental processes of the mind are the
Sense-Perceptive Process and the Judicial Process.

So far you have considered only the former--that is to say,
sense-impressions and our perception of them. You have learned through
an analysis of this process that the environment that prescribes your
conduct and defines your career is wholly mental, the product of your
own selective attention, and that it is capable of such deliberate
molding and adjustment by you as will best promote your interests.

But the mere perception of sense-impressions, though a fundamental
part of our mental life, is by no means the whole of it. The mind is
also able to look at these perceptions, to assign them a meaning and
to reflect upon them. These operations constitute what are called the
Judicial Processes of the Mind.

The Judicial Processes of the Mind are of two kinds, so that, in the
last analysis, there are, in addition to sense-perceptions, two, and
only two, types of thought.

One of these types of thought is called a Causal Judgment and the
other a Classifying Judgment.

CHAPTER II

CAUSAL JUDGMENTS

A Causal Judgment interprets and explains sense-perceptions. For
instance, the tiny baby's first vague notion that _something_, no
knowing what, must have caused the impressions of warmth and
whiteness and roundness and smoothness that accompany the arrival
of its milk-bottle--this is a causal judgment.

[Sidenote: _Elementary Conclusions_]

The very first conclusion that you form concerning any sensation that
reaches you is that something produced it, though you may not be
very clear as to just what that something is. The conclusions of the
infant mind, for example, along this line must be decidedly vague and
indefinite, probably going no further than to determine that the cause
is either inside or outside of the body. Even then its judgment may
be far from sure.

[Sidenote: _First Effort of the Mind_]

Yet, baby or grown-up, young or old, the first effort of every human
mind upon the receipt and perception of a sensation is to find out
what produced it. The conclusion as to w
