ces of _actual_ experience belonging to the same subject,
with definite tracts of conjunctive transitional experience between
them; or

(3) the known is a _possible_ experience either of that subject or
another, to which the said conjunctive transitions _would_ lead, if
sufficiently prolonged.

To discuss all the ways in which one experience may function as the
knower of another, would be incompatible with the limits of this
essay.[30] I have just treated of type 1, the kind of knowledge called
perception.[31] This is the type of case in which the mind enjoys direct
'acquaintance' with a present object. In the other types the mind has
'knowledge-about' an object not immediately there. Of type 2, the
simplest sort of conceptual knowledge, I have given some account in two
[earlier] articles.[32] Type 3 can always formally and hypothetically be
reduced to type 2, so that a brief description of that type will put the
present reader sufficiently at my point of view, and make him see what
the actual meanings of the mysterious cognitive relation may be.

Suppose me to be sitting here in my library at Cambridge, at ten
minutes' walk from 'Memorial Hall,' and to be thinking truly of the
latter object. My mind may have before it only the name, or it may have
a clear image, or it may have a very dim image of the hall, but such
intrinsic differences in the image make no difference in its cognitive
function. Certain _extrinsic_ phenomena, special experiences of
conjunction, are what impart to the image, be it what it may, its
knowing office.

For instance, if you ask me what hall I mean by my image, and I can
tell you nothing; or if I fail to point or lead you towards the Harvard
Delta; or if, being led by you, I am uncertain whether the Hall I see be
what I had in mind or not; you would rightly deny that I had 'meant'
that particular hall at all, even though my mental image might to some
degree have resembled it. The resemblance would count in that case as
coincidental merely, for all sorts of things of a kind resemble one
another in this world without being held for that reason to take
cognizance of one another.

On the other hand, if I can lead you to the hall, and tell you of its
history and present uses; if in its presence I feel my idea, however
imperfect it may have been, to have led hither and to be now
_terminated;_ if the associates of the image and of the felt hall run
parallel, so that each term of the one context
