We would indeed have a logical problem were one to claim it is both true and false that "A photon is a particle and ..." And clearly there is nothing illogical about claiming that photons exhibit some properties of waves and some properties of particles. Or: "Photons may be considered to be waves for certain purposes and particles for other purposes." And what they are "in themselves" is of interest only to a particular kind of philosopher.
