In his dialogue the Timaeus, Plato recognized two aspects of time, the past and the future, but not the present. In contrast, Aristotle's analysis of time in the Physics took its orientation from the 'now'. It is the latter path that Husserl follows with his conception of the 'original impression' (Urimpression). However, in certain parts of Husserl's Bernau Manuscripts, the present loses significance because of a novel interpretation of protention. This development, which revitalizes Plato's understanding of time, is furthered in Heidegger's late lecture Time and Being: the present can be understood on the basis of the 'withdrawal' which determines the mutual relation between the arrival as authentic future and the having-been as authentic past.

Through the philosophies of Bergson and Deleuze, my paper explores a different theory of time. I reconstitute Deleuze’s paradoxes of the past in Difference and Repetition and Bergsonism to reveal a theory of time in which the relation between past and present is one of coexistence rather than succession. The theory of memory implied here is a non-representational one. To elaborate this theory, I ask: what is the role of the “virtual image” in Bergson’s Matter and Memory? Far from representing the simple afterimage of a present perception, the “virtual image” carries multiple senses. Contracting the immediate past for the present, or expanding virtually to hold the whole of memory (and even the whole of the universe), the virtual image can form a bridge between the present and the non-representational past. This non-representational account of memory sheds light not only on the structure of time for Bergson, but also on his concepts of pure memory and virtuality. The rereading of memory also opens the way for Bergsonian intuition to play an intersubjective role; intuition becomes a means for navigating the resonances and dissonances that can be felt between different rhythms of becoming or planes of memory, which constitute different subjects.

The prosaic content of these sayings is that events change from future to present and from present to past. Your next birthday is in the future, but with the passage of time it draws nearer and nearer until it is present. 24 hours later it will be in the past, and then lapse forever deeper into history. And things get older: even if they don’t wear out or lose their hair or change in any other way, their chronological age is always increasing. These changes are universal and inescapable: no event could ever fail to be first future, then present, then past, and no persisting thing can avoid growing older. We call this process time’s passage.

The view of time basically depends on the given society and its relation to nature and its economy. Based on the connection of past, present, and future to each other, two systems can be differentiated: cyclical time and linear time. In societies of cyclical time the individual is responsible for nature as part of the community. Today the aim of life is defined by the linear nature of time. If we assume responsibility for the entire Earth then the role of time changes. We need to expand our time horizon, rediscover the past, and study the future.

A set of eight mini-discourses. 1. The conceivability of the physical world's running in the opposite temporal direction. 2. Augustine's reason for thinking this is not conceivable for the world of the mind. 3. Trying to imagine being a creature that lives atemporally. 4. Memory's need for causal input. 5. Acting in the knowledge that how one acts is strictly determined. 6. The Newcomb problem. 7. The idea that all voluntary action is intended to be remedial. 8. Haunted by the strangeness of the idea of the past qua past.

There is a tension between the “growing block” account of time (closed past, open future) and the possibility of backwards time travel. If Tim the time traveler can someday travel backwards through time, then he has (in a certain sense) already been. He might discover this fact before (in another sense) he goes. Hence a dilemma: it seems that either Tim’s future is determined in an odd way or cases of (temporary) ontic indeterminate identity are possible. Either Tim cannot avoid heading for the past or he is only indeterminately that guy who appeared in the past with many of Tim’s memories. Determinacy in the past implies a degree of determinism in the future; indeterminism about the future seeps back to the past.

Memory is, therefore, neither perception nor conception, but a state or affection of one of these, conditioned by lapse of time. As already observed, there is no such thing as memory of the present while present; for the present is object only of perception, and the future, of expectation, but the object of memory is the past. All memory, therefore, implies a time elapsed; consequently only those animals which perceive time remember, and the organ whereby they perceive time is also that whereby they remember. (Aristotle, OM, 449b24–30).

Much of ordinary memory is autobiographical; memory of what one saw and did, where and when. It may derive from your own past experiences, or from what other people told you about your past life. It may be phenomenologically rich, redolent of that autumn afternoon so long ago, or a few austere reports of what happened. But all autobiographical memory is first-person memory, stateable using ‘I’. It is a memory you would express by saying, ‘I remember I . . .’.

Time and Memory throws new light on fundamental aspects of human cognition and consciousness by bringing together, for the first time, psychological and philosophical approaches dealing with the connection between the capacity to represent and think about time, and the capacity to recollect the past. Fifteen specially written essays offer insights into current theories of memory processes and of the mechanisms and cognitive abilities underlying temporal judgements, and draw out key issues concerning the phenomenology and epistemology of memory and its role in our understanding of time.

Book description: The capacity to represent and think about time is one of the most fundamental and least understood aspects of human cognition and consciousness. This book throws new light on central issues in the study of the mind by uniting, for the first time, psychological and philosophical approaches dealing with the connection between temporal representation and memory. Fifteen specially written essays by leading psychologists and philosophers investigate the way in which time is represented in memory, and the role memory plays in our ability to reason about time. They offer insights into current theories of memory processes and of the mechanisms and cognitive abilities underlying temporal judgements, and draw out fundamental issues concerning the phenomenology and epistemology of memory and our understanding of time. The chapters are arranged into four sections, each focused on one area of current research: Keeping Track of Time, and Temporal Representation; Memory, Awareness and the Past; Memory and Experience; Knowledge and the Past: The Epistemology and Metaphysics of Time. A general introduction gives an overview of the topics discussed and makes explicit central themes which unify the different philosophical and psychological approaches.
