Michael Tooley presents a major new philosophical study of time and its relation to causation. The nature of time has always been one of the most fascinating and perplexing problems in philosophy. In recent years, it has become the focus of vigorous debate between advocates of rival theories, as traditional, 'tensed' accounts of time, which hold that time has a direction and that the flow of time is part of the nature of the universe, have been challenged by 'tenseless' accounts of time, according to which past, present, and future are merely subjective features of events, rather than objective properties of events.

"The work of the late William Sutherland was well known in detail to very few people by reason of its advanced character, but many Australians were aware of its high reputation. The signatories to this introduction have taken steps, now that he has passed away, to place on record an account of his life and work. They have entrusted the fulfilment of this intention to Dr. W.A. Osborne, Professor of Physiology in the the University of Melbourne, who has generously exerted himself to do justice to the memory of this distinguished graduate. William Sutherland was known to a limited circle of friends, who appreciated to the full not only his ability, but still more his remarkable personality - an earnest, selfless, many-sided man removed from the affairs of the business world, asking only that he should be allowed to do a third of a day's work so that he might devote the remaining portion of the day to the studies that were dear to him. Yet he was no recluse and brought to bear on worldly affairs a most original, penetrating and comprehensive criticism of human motives and tendencies. No appeal to help in matters of knowledge was ever made to him in vain; in fact, so affectionate was his disposition, that refusal was impossible. The signatories have done all that is possible for them to render homage to the memory of a man who so materially enriched the world. P. Baracchi, J.W. Barrett (Hon. Sec.), H.B. Higgins, T.R.
