  Suppose that I am riding my bicycle from my home to the university. Suddenly I realise that I have crossed a bridge over a creek, gone along a twisty path for half a mile, avoided oncoming traffic, and so on, and yet have no memories of all this. In one sense I was conscious: I was perceiving, getting information about my position and speed, the state of the bicycle track and the road, the positions and speeds of approaching cars, the width of the familiar narrow bridge. But in another sense I was not conscious: I was on ‘automatic pilot’. So let me use the word ‘awareness’ for this automatic or subconscious sort of consciousness. Perhaps I am not one hundred percent on automatic pilot. For one thing I might be absent minded and thinking about philosophy. Still, this would not be relevant to my bicycle riding. One might indeed wonder whether one is ever one hundred percent on automatic pilot, and perhaps one hopes that one isn't, especially in Armstrong's example of the long distance truck driver (Armstrong 1962). Still it probably does happen, and if it does the driver is conscious only in the sense that he or she is alert to the route, of oncoming traffic etc., i.e. is perceiving in the sense of ‘coming to believe by means of the senses’. The driver gets the beliefs but is not aware of doing so. There is no suggestion of ineffability in this sense of ‘consciousness’, for which I shall reserve the term ‘awareness’.
