the bird. Intelligence is hardly to any extent a necessity of the
vital union of the Will with the energetic system. It is not at all
developed in the vegetal kingdom, hardly at all in some branches of the
animal, and there may conceivably be an infinite number of other
"kingdoms" in which it may be either undeveloped, or very differently
developed, or superseded by some other manifestation by us unimaginable.
Its development indeed seems to be concurrent with the development of a
locomotive faculty--a striking confirmation of the theory that it is in
our activity that we derive the suggestions which call forth the
exercise of the Understanding and transform sensation into perception.

It is only with a comparative fraction of the organism that I am related
as a passively percipient intelligence. I am directly or indirectly
related as Will, as an originative cause of activity, with a larger
portion of my organism, many parts of which are quite distinct from the
cognitive portion. Now it is from my relation as Will with Energy other
than and beyond the energetic transmutations which constitute my
Presentment that I discover the energetic system of Nature, as a real
thing--beyond, underlying, and by its transmutations constitutive of my
Presentment. Many of the transmutations which occur in my Presentment I
recognise as attributable to my own volitional activity operating upon
my energetic organism, and _in my own activity there is thus suggested
to me a source of phenomena lying beyond these phenomena themselves_. A
transmutation initiated in my brain is a pure idea. The key which
suggests to me the real world is the occurrence of transmutations
ascribable to my activity operating beyond the sphere which constitutes
my Presentment.

It is in this way that I originally discover the real energetic
substratum to the phenomenal world of my Presentment. I learn from the
transmutations to infer the agency and operation of the underlying
energy, and thus gradually construct my whole systematic conception of
the real world in which I live and move and have my being.

This view of my activity and of the consequences of my relation as Will
to the energetic system represented by my organism, including the
portion thereof related to my intelligence, supplies us therefore with a
key to the inevitable reference of thoughts to things.

I distinguish in my active experience a clear difference between wishing
and willing, and further
