ysical affect, pleasurable or painful

_Thinking_ is a conscious mental activity exercised to evolve ideas from
perceptions, and to combine and compare these ideas to form judgments.

Intellection, or thinking, might be explained as the mental process
which converts sensation into percepts, groups percepts to form concepts
or ideas, stores away ideas and sensations for future use, and recalls
them when needed--the recalling being memory--and by reason combines,
compares, and associates ideas to form judgments, then compares
judgments to form new judgments. The process of intellect we name by
terms denoting activity, such as intellection, thinking, the _stream of
thought_, and the latter describes it most truly.

_Volition_ or _will_ is the function of the mind which compels the
expression of thought or feeling in action.

For clarity we might indicate the mind and its functions in the
following diagram:

/ Emotion { Pleasure \
{ { Pain }
{ / Eye }
{ { Ear }
{ / Sensation / Nose }
{ { (impression < Mouth }
{ { on mind from \ Skin }
{ { some organs) { Muscles }
