Abstract
Following P. A. M. Dirac's critique in ``Lectures on Quantum Field Theory'' of the usual formalism, I will discuss the role of the time parameter to solve R. Haag's no-go theorem on the non-equivalence of the conventional Schr\"odinger picture and the Heisenberg picture. This is possible by first defining in a correct way the concept of the vacuum state at a given time in relativity. I will also discuss some consequences such as the spectral condition.
