For the present we note his remark in this paper: "A hole, if there were one, would be a new kind of particle, unknown to experimental physics, having the same mass and opposite charge of the electron" The fight was not over. ...

This is based on the following components: i) a sound and complete classical logic axiomatisation of the semantics of the object logic L, ii) a domain-dependent notion of “acceptability” for th ...
