No doubt, if Julian had wanted to be simply Emperor, he should and could have given up completely those mockings and stopped his subtle jesting. Having remained a philosopher, however, he could not abandon philosophic pedagogy; in addressing his writings only to a mature elite, he took care that the tradition of what was for him the (discursive) truth should not be interrupted. The camouflaged mocking which escapes the vulgar permits the selection of strong minds who understand such ironies without being shocked by them, and who thus reveal that they are not so enslaved by prejudices as to be unapt to receive, perhaps with some benefit, a philosophic instruction which will itself be given them only between the lines for the same reason of selection and secrecy.
