Abstract
What we experience is somewhat of a melange, something at once perceptual, mediated by the sense organs; scientific, reflecting our use of mathematical and other formal devices to make clear and systematic the causes of what is now taking place, and pointing us towards what might be expected; eventful, stretches of vital movement in which beginning and ending are, though separate, inescapably interlocked; and important, reflecting both our sense of value and the presence of an objective standard outside us and unaffected by our interests. Initially these strands are inchoately together, constituting commonsense objects, artifactual or natural, the occupants of the world of which we unreflectively take account. On some occasions one of these facets may be to the fore, on other occasions it may be so recessive that its presence is overlooked.
