Abstract

Turning from classical to quantum physics, new problems arise with regard to the traditional philosophical question of what a "physical object" is. A recent "group-theoretical" approach to the question as to whether it does make sense to speak of "quantum objects' is illustrated, investigating the connection it affords with the traditional problem of the "objectivity" of physical knowledge. The individuality issue for quantum particles is also taken into account.
