I agree that what the "particle actually is" falls outside of physics and is best left to philosophy. It is only when (or if) physics attaches an ultimate reality to such entities that we should start to worry about what this means. As long as physicists are clear in what they mean by "particles" then there is no danger of any misrepresentation in the manner that I thought may have been the case here:
