NOTES

1 We shall consider later what the Theory of Relativity has to say as to the impossibility of separating time and space and as to the notion of one single time-series.

2 It is better for the present not to call these states of mind either perceptions or sensations, because the object of a perception is generally supposed to be a physical object or its state, and this may exist millions of years before the perception -- e.g., the perception of a distant star. Similarly, to call these states of mind sensation would lead to misunderstandings, owing to the ambiguities of that word and the widely held belief that sensations do not have objects.

3 The point can perhaps be made clearer by reflecting that a tune has a pattern in time in exactly the same sense as a wall-paper has a pattern in space.

4 We can, of course, remember much that we could not infer.

5 The universe here must be taken to include God, if there be one.
