It is the field directly perceived.

But the entities of this field have relations to other entities which are not particularly discriminated in this individual way.

These other entities are known merely as the relata in relation to the entities of the discerned field.

Such an entity is merely a 'something' which has such-and-such definite relations to some definite entity or entities in the discerned field.

As being thus related, they are--owing to the particular character of these relations--known as elements of the general fact which is going on.
