140 STONEY—UNIVERSE OF REAL EXISTENCES. [April 3, 
available just at those points where the assumptions usually made 
by scientific men leave us in the lurch—as when we are brought 
face to face with the problem of the true relation between a man’s 
thoughts and the events in his brain associated with them ; or when 
the problem is to ascertain of what kind are the true efficient causes 
of those events that occur about us in nature. 
APPENDIX. 
In the foregoing pages the author has freely used passages ex- 
tracted from others of his writings, altering them and adding to 
them so as to obviate, as much as in him lay, difficulties which 
have been felt by some of the readers of those preceding papers ; 
and his hope is that none of these difficulties will be felt in reading 
the present essay. 
The attempt has been made to keep to that one special path 
through the territory opened up to us by the study of ontology, 
which pursues its way among the topics of most use tous as scientific 
students of nature. But much may be learned by other excursions 
into this great field of exploration, and they end in presenting us 
with a spectacle of unsurpassed sublimity. 
It may be well so far to trespass upon this new ground as to men- 
tion some results of the further inquiry. In certain parts of the 
new territory we have to venture on less firm ground than that 
which we have trodden in the preceding essay, and must be content 
with results arrived at with probability. It is then found that such 
evidence as can be brought to bear appears to tend with consider- 
able emphasis to the conclusion that not only the auta that are our 
minds are thoughts, but that the same is true of the auta that 
are our synergos. Now the mind and its synergos are, when taken 
together, the antitheton or true autic existence corresponding to the 
objective brain. A similar conclusion is indicated with regard to 
the rest of objective nature. The antitheta of the objective events 
—the true autic events which corréspond to them—seem, with a 
considerable degree of probability, to be essentially thoughts; 
most of them no doubt with vastly different time relations to those 
of the thoughts that are the human mind, but still in several mate- 
rial respects not unlike them. If this view is correct, the only 
things that [really] exist are thoughts, and the effects produced by
