 If McTaggart’s argument that passage is conceptually absurd or self-contradictory fails, philosophers mindful of modern physics are still left with Einstein’s concern that passage and the now, while deeply embedded in human experience, seem to find no place in physics. One may agree with Carnap above that “all that occurs objectively can be described in science” and then argue that passage reflects something perspectival or subjective and so is rightly omitted by physics.
