gression ; whereas at one stage we may find ourselves in want of 
knowledge that cannot be satisfactorily dealt with till some subse- 
quent stage. We are in this predicament at present. For further 
progress in this inquiry it is essential that we shall know something 
about the synergos (ovvepyés , a coadjutor or co-operator) which is 
associated with my mind in all, or almost all, its operations, 
which contributes largely to every message that my mind receives 
from abroad, and to every message that comes down to it through 
memory from its own earlier experiences; and without which my 
mind would, in fact, be an absolute blank as regards all that is 
going on outside itself, and would be destitute of any knowledge of 
its own past thoughts. As the relations between this synergos and 
the mind have to be dealt with prematurely, the reader is requested 
to pardon the intrusion into this chapter of matter which cannot be 
adequately expounded till farther on. 
The [events]’ in a man’s brain! which are associated with the 
thoughts that are his mind, do not occur except while the man is 
alive ; and only, during life, when he is either awake or dreaming. 
All these objective events can be shown to resolve themselves in 
ultimate analysis into motions of one kind or another going on in, 
or in connection with, the brain. But they are far from being the 
whole of the motions of which (under the diacrinominal view of 
nature, see Chapter 17) the brain consists—in fact, they are an exces- 
sively small and quite peculiar selection from the totality of motions 
that are the brain. It is possible to satisfy ourselves of this by in- 
stituting a comparison of time relations. Accordingly, a bystander 
would see this selection of motions going on in my brain while lam 
awake, if he could make it an object of observation, and if his 
senses were acute enough to see all that is going on objectively. 
If, however, he could see all that is going on objectively, he 
would see a vast deal more than the changes or motions that are 
associated with my thoughts. We thus, and from other evidence, 
learn that the aitio-brain—the source in the autic universe of the 
perceptions and ultra-perceptions which make up that object of 
nature which we call the brain—is a collection of auta which in- 
cludes many more auta besides those that are my mind: and these 
‘many more auta’ are the synergos. 
1 By [events]’ is to be understood events in the od/ective world which we call 
nature. If written [events], without the dash, it would denote events in the 
universe of auta.
