cogredient

There is not only a significance of the discerned events embracing the whole present duration, but there is a significance of a cogredient event involving its extension through a whole time-system backwards and forwards.

I may take this opportunity of pointing out that the 'stationary events' of article 57 of the _Principles_ are merely cogredient events got at from an abstract mathematical point of view.

The stream of events which form the continuous series of situations of the electron is entirely self-determined, both as regards having the intrinsic character of being the series of situations of that electron and as regards the time-systems with which its various members are cogredient, and the flux of their positions in their corresponding durations.

It is not true that all the parts of an event cogredient with a duration are also cogredient with the duration.

If an event e be cogredient with a duration d, and d′ be any duration which is part of d.

Also d′ intersects e in an event e′ which is part of e and is cogredient with d′.

For example, the tunnel of a tube railway is an event at rest in a certain time-system, that is to say, it is cogredient with a certain duration.

Consider the aggregate of events in which P lies and which are also cogredient with d.

To sum up, a duration and a percipient event are essentially involved in the general character of each observation of nature, and the percipient event is cogredient with the duration.

In this case the part may be cogredient with another duration which is part of the given duration, though it is not cogredient with the given duration itself.
