112 STONEY—UNIVERSE OF REAL EXISTENCES. [April 3, 
We may also use the term wmverse to mean the Zofality of these 
auta. To prevent confusion, it may be well to designate the 
totality of natural objects by some other name. We may call it 
nature, or the cosmos, reserving the term universe for ‘he fofality of 
auta. Or, if at any time the word wmzverse is applied to the totality 
of natural objects, it may be written with a dash, the objective 
[universe]’, to distinguish it unmistakably from the autic [universe]. 
It is to be noted that here and elsewhere the word /ofality is to be 
understood as having a more comprehensive’ meaning than the 
word aggregate. .Any collection of auta, however disorderly, 
would be an aggregate of those auta. By their /ofality is to be 
understood those auta, uuder one definite set of conditions—viz. : 
under the conditions that actually prevail—with those mutual rela- 
tions, performing those operations, undergoing those changes that 
actually occur. 
CHAPTER 5. IN WHAT SENSE THE TERM ¢hought 1s EMPLOYED. 
We shall want a term which is applicable to everything of which 
T or my fellow-men or the lower animals can be conscious ; and as 
at present no word in the English language has this wide significa- 
tion, we shall extend or generalize the meaning of the term ¢hought, 
so as to make it serve. Accordingly ¢hough?t, in the generalized 
sense in which we shall use it, embraces sensations, perceptions, be- 
liefs, feelings, memories, emotions, sentiments, judgments, motives, 
acts of will, and so on—in fact, everything which comes within the 
consciousness of any animal. I shall also use the term J, or the 
ego, or my mind, to denote the totality (not the mere aggregate) of 
a certain group of these thoughts, which may be spoken of as my 
thoughts. Observe that the word mind is here used in one of the 
two significations which it has in the English language, and that it 
will not in the present essay be used in the other of those senses. 
Accordingly, in the present essay, the term znd will not be used 
to signify the ‘ spiritual substance’ which, according to a view very 
widely entertained, is supposed to be in existence, as well as the 
1JIn Formal Logic the comprehension of a term is the collection of ideas 
which are included in the definition of the term. Accordingly, the greater the 
comprehension of a term, the fewer will be the individuals to whom that term 
can be applied. This is expressed in Logic by saying that the greater the com- 
prehension of a term, the less is its extension. For example, Spaniard is a term 
which has a greater comprehension and a less extension than European.
