The book has two purposes, a negative one and a positive one, which are complementary. The negative one is to challenge the 'hijacking' of time in popular versions of modern mathematical and scientific thought, which have tended to push out of the picture views of time which do not 'fit in' with modern physics. The second purpose is to show how, by supplementing, or sometimes overriding, the scientific perspective, a wider understanding is reached. Time cannot be described in terms of its measurement alone.
