the various forms of physical energy, and coming in either be- 
fore or alongside of or subsequent to the operation of this phys- 
ical energy. The psychical is the meaning of the operation of 
the forces in the material world. 
This is the element of truth in all doctrines of parallelism, 
that existence always has meaning and meaning always refers 
to existence, that structure reveals its significance in function 
and function is but another name for the significance of struc- 
ture—and this view is as far from materialism as it is from the 
opposite error of subjective idealism. 
We have said that the ideas of the physical and the psy- 
chical in the sense of existence and meaning emerge together 
in experience. But not all our experience is characterized by 
a clear distinction of these two. There was a time both in the 
experience of the race and in individual development when 
these were only vaguely held apart.

In other words, the evolution of the distinction of fact and 
meaning, or existence and significance, has been by slow de- 
grees, and we say that a consciousness is of a relatively low or 
high type according to the clearness with which this distinction 
is made. There is something in the experience of the savage 
and of the child which corresponds to what the philosopher or 
the scientist calls the fact and the meaning of the fact. More 
than this, there is in the experience of every conscious being, 
however low in the scale of life, something which corresponds 
to this same distinction. Wherever there is consciousness there 
is this distinction between the psychical and the physical in this 
sense of function and structure, or meaning and the fact of 
which it is the meaning; there is a distinction between some- 
thing taken as actual (as fact or existence) and something taken 
as ideal (as meaning or significance). 
With this point of view in mind, let us pass now to the
