Sir David Ross, Ladies And Gentlemen: I Have chosen as the topic of this inaugural lecture that of “having in mind,” the manner or manners in which things come before us in consciousness, are present to our thoughts, or are in some way “there for us.” Alternatively, I might say that I want to consider whatever may be involved in saying that we can turn our thoughts in this or that direction, that we can let them dwell on this or that actuality or possibility, whether what we thus concern ourselves with be picked out from our present environment, or reached for beyond it. I like this second “active” way of describing my subject-matter much less than my first, impersonal way of speaking, for reasons that I shall try to make plain in the course of this lecture. I wish, in short, to give you a tentative anatomy of our conscious life, and to sketch the fundamental dimensions into which it may be differentiated. This task is important, since the puzzles which concern the presence of objects to our minds are of a peculiarly deep-seated and refractory sort: they are also puzzles which infect our treatment of practically all other philosophical questions. It is not that certain arbitrarily chosen ways of speaking confuse us, which could be readily bettered by keeping our eyes on the facts: it is rather as if our subject-matter itself confused us, and tempted us to describe it in ways which only serve to deepen mystery and perplexity, and which ultimately plunge us into nonsense.
