Abstract
This paper discusses the view according to which time is not an objective feature of reality, independent of the knowing subject. Rather than attempting to provide an exhaustive historical reconstruction of the debate concerning the (un)reality of time, we will proceed by looking at two paradigmatic and rather different arguments to the effect that time is an illusion: a well-known, purely philosophical argument due to McTaggart, and an argument (or, maybe better, a family of considerations) coming from contemporary research in physics, in particular quantum gravity. Interesting common aspects will be emphasized and, in closing, a few more general considerations will be made.
