This is Volume VIII of five of the Epistemology and Metaphysics series. First published in 1951, this book is an essay towards a theory of knowledge, and an attempt to detect and identify some changes of general outlook in the epistemological field which seem to be taking place in our society.

I.e. this chapter is a discussion of the more general theory or attitude which sets the limits within which all such theories about time must fall. (Cf. page 33.)For this reason, certain distinctions which would ordinarily be made between different meanings of 'time' need not be introduced here, for instance the distinction between 'time' envisaged as a bird gliding over a series of hedgerows and 'time' envisaged as the hedgerows. Thus this chapter is not an erratic alternation between the discussion of time in one sense and time in various other senses, but is a discussion of the more general theory in terms of which alone it is possible to distinguish these various senses; Chapter 10 Space; Chapter 11 Qualities; Part 3 Essay to Wards a Theory of Knowledge; Chapter 12 Facts; Chapter 13 Knower and Known; Chapter 14 Language and Statement; Chapter 15 Attitudes; Chapter 16 Appearance and Reality; Chapter 17 Sensations, Perceptions, Feelings, Emotions and Things; Chapter 18 Meaning; Chapter 19 Truth; Chapter 20 Inference and Explanation; Chapter 21 The Criterion;
