Otherwise it is a matter of judgment and inference.
The situations of a sense-object are not conditioned by any such conditions either of uniqueness or of continuity.

In any durations however small a sense-object may have any number of situations separated from each other.

Thus two situations of a sense-object, either in the same duration or in different durations, are not necessarily connected by any continuous passage of events which are also situations of that sense-object.
The characters of the conditioning events involved in the ingression of a sense-object into nature can be largely expressed in terms of the physical objects which are situated in those events.

In one respect this is also a tautology.

For the physical object is nothing else than the habitual concurrence of a certain set of sense-objects in one situation.
Accordingly when we know all about the physical object, we thereby know its component sense-objects.
