y exposition to 'external'
reality. But there is also the system of ideal reality in which the room
plays its part. Relations of comparison, of classification, serial
order, value, also are stubborn, assign a definite place to the room,
unlike the incoherence of its places in the mere rhapsody of our
successive thoughts. [Cf. above, p. 16.]

[16] Note the ambiguity of this term, which is taken sometimes
objectively and sometimes subjectively.

[17] In the _Psychological Review_ for July [1904], Dr. R. B. Perry has
published a view of Consciousness which comes nearer to mine than any
other with which I am acquainted. At present, Dr. Perry thinks, every
field of experience is so much 'fact.' It becomes 'opinion' or 'thought'
only in retrospection, when a fresh experience, thinking the same
object, alters and corrects it. But the corrective experience becomes
itself in turn corrected, and thus experience as a whole is a process in
which what is objective originally forever turns subjective, turns into
our apprehension of the object. I strongly recommend Dr. Perry's
admirable article to my readers.

[18] I have given a partial account of the matter in _Mind_, vol. X, p.
27, 1885 [reprinted in _The Meaning of Truth_, pp. 1-42], and in the
_Psychological Review_, vol. II, p. 105, 1895 [partly reprinted in _The
Meaning of Truth_, pp. 43-50]. See also C. A. Strong's article in the
_Journal of Philosophy, Psychology and Scientific Methods_, vol. I, p.
253, May 12, 1904. I hope myself very soon to recur to the matter. [See
below, pp. 52 ff.]

[20] Spencer's proof of his 'Transfigured Realism' (his doctrine that
there is an absolutely non-mental reality) comes to mind as a splendid
instance of the impossibility of establishing radical heterogeneity
between thought and thing. All his painfully accumulated points of
difference run gradually into their opposites, and are full of
exceptions. [Cf. Spencer: _Principles of Psychology_, part VII, ch.
XIX.]

[21] I speak here of the complete inner life in which the mind plays
freely with its materials. Of course the mind's free play is restricted
when it seeks to copy real things in real space.

[22] [But there are also "mental activity trains," in which thoughts do
"work on each other." Cf. below, p. 184, note. ED.]
