He implies, therefore, that the object of a conception can be said to
be possible only when the conception is the apprehension of a complex
of elements together with the apprehension--which, if not _a priori_,
must be based upon experience--that they are connected. Hence a
conception may be regarded as 'objectively real', or as 'fictitious'
according as it is the apprehension of a complex of elements
accompanied by the apprehension that they are connected, or the
apprehension of a complex of elements not so accompanied.
[4] The view that 'in the mere conception of a thing no sign
of its existence is to be found' (B. 272, M. 165) forms, of
course, the basis of Kant's criticism of the ontological
argument for the existence of God. Cf. _Dialectic_, Bk. II,
Ch. III, § 4.
[5] Cf. 'a conception which includes in itself a synthesis'
(B. 267 med., M. 162 med.).

The formulation which really expresses Kant's thought is to
be found B. 266 med., M. 161 fin.; B. 268 init., M. 162 fin.;

It is now possible to state Kant's problem more precisely. With regard
to a given complex conception he wishes to determine the way in which
we can answer the questions (1) 'Has the conception a possible object
to correspond to it', or, in other words, 'Is the conception
'objectively real' or 'fictitious'?' (2) 'Given that a corresponding
object is possible, is it also real?' (3) 'Given that it is real, is
it also necessary?'
