  It is usually believed that a picture of Quantum Mechanics in terms of true
probabilities cannot be given due to the uncertainty relations. Here we discuss
a tomographic approach to quantum states that leads to a probability
representation of quantum states. This can be regarded as a classical-like
formulation of quantum mechanics which avoids the counterintuitive concepts of
wave function and density operator. The relevant concepts of quantum mechanics
are then reconsidered and the epistemological implications of such approach
discussed.
