We shall find nothing in it except what we have put there to represent the ideas in thought which arise from our direct sense-awareness of nature.

To find evidence of the properties which are to be found in the manifold of event-particles we must always recur to the observation of relations between events.

Our problem is to determine those relations between events which issue in the property of absolute position in a timeless space.

This is in fact the problem of the determination of the very meaning of the timeless spaces of physical science.
In reviewing the factors of nature as immediately disclosed in sense-awareness, we should note the fundamental character of the percept of 'being here.' We discern an event merely as a factor in a determinate complex in which each factor has its own peculiar share.
There are two factors which are always ingredient in this complex, one is the duration which is represented in thought by the concept of all nature that is present now, and the other is the peculiar _locus standi_ for mind involved in the sense-awareness.

This _locus standi_ in nature is what is represented in thought by the concept of 'here,' namely of an 'event here.' This is the concept of a definite factor in nature.
