Abstract: In this paper I give consideration to some apparent impossibilities for the time travelers to the past. After criticizing the views of D. Lewis and K. Vihvelin, I will show in what sense they are really impossible.Thomson, Judith Jarvis. McTaggart on Time2001, Noûs 35(s15): 229-252.-

Introduction: McTaggart's argument for the conclusion that time does not exist is notoriously hard to understand. C. D. Broad says that when properly interpreted, its main part can be seen to be "a philosophical 'howler'." Others see things in it that they regard as true and important, or if not true, then anyway important. But I have not seen any interpretation of it that seems to me to get it exactly right. And I think that it pays to get it right: there are lessons to be learned from consideration of what goes on in it. By way of reminder, McTaggart's argument has two parts. The first part aims at the conclusion that time does not exist unless the A series exists. The second part aims at the conclusion that the A series does not exist. It follows that time does not existComment: One of the clearest statements of McTaggart's argument about time; the interpretation is well-argued for. Very helpful as an aid to comprehension if McTaggart's argument is taught, as it usually would be in any examination of philosophy of time.

Introduction: Things change: objects come into existence, last for a while, go out of existence, move through space, change their parts, change their qualities, change in their relations to things. All this would seem to be uncontroversial. But philosophical attention to any of these phenomena can generate perplexity and has resulted in a number of long-standing puzzles. One of the most famous puzzles about change threatens to demonstrate that nothing can persist through time, that all existence is momentary at best. Let's use the term 'alteration' for the sort of change that occurs when a persisting object changes its properties.Comment: A good overview of the philosophical issues involved in persistence through time. Would be a good preliminary material in a philosophy of time course. Or, since this is a fundamental philosophical problem, could be used in an introduction to philosophy course as a more clear alternative or supplement to ancient sources.

Introduction: But what if in order to save one’s life one has to kill another person? In some cases that is obviously permissible. In a case I will call Villainous Aggressor, you are standing in a meadow, innocently minding your own business, and a truck suddenly heads toward you. You try to sidestep the truck, but it turns as you turn. Now you can see the driver: he is a man you know has long hated you. What to do? You cannot outrun the truck. Fortunately, this is not pure nightmare: you just happen to have an antitank gun with you, and can blow up the truck. Of course, if you do this you will kill the driver, but that does not matter; it is morally permissible for you to blow up the truck, driver and all, in defense of your life.Comment: The text discusses permissible and excusable self-defence reactions towards different types of aggressors. It is useful in teaching on issues involving the doctrine of double effect.
