 This view has been attacked on a number of counts. First, acts of lying are datable; when someone lies they do so at a particular time, in a particular place, and to a particular audience. While the content of a false assertion may concern the future, the lie occurs at the time of utterance. If someone fails to do what they said she would, she does not lie at that later time, for at that later time she asserts nothing. Nor does she lie when she says she will do it because, ex hypothesi, she sincerely believed at that time that she would. If the deed does not follow her words she may be guilty of many things: weakness of will, or laziness, cowardice, pusillanimity, depending on the circumstances. If she has led someone to rely on her earlier assertion, she may be accused of breach of faith, or going back on her word. But what she is not guilty of is lying. She would only be guilty of that if she was not expressing a sincere belief when she made the original assertion.
