Acts 26:24 - Clarke's commentary and critical notes on the Bible

And as he thus spake for himself, Festus said with a loud voice, Paul, thou art beside thyself; much learning doth make thee mad. Paul, thou art beside thyself - "Thou art mad, Paul!" "Thy great learning hath turned thee into a madman." As we sometimes say, thou art cracked, and thy brain is turned. By the τα πολλα γραμματα it is likely that Festus meant no more than this, that Paul had got such a vast variety of knowledge, that his brain was overcharged with it: for, in this speech, Paul makes no particular show of what we call learning; for he quotes none of their celebrated authors, as he did on other occasions; see Acts 17:28. But he here spoke of spiritual things, of which Festus, as a Roman heathen, could have no conception; and this would lead him to conclude that Paul was actually deranged. This is not an uncommon case with many professing Christianity; who, when a man speaks on experimental religion, on the life of God in the soul of man - of the knowledge of salvation, by the remission of sins - of the witness of the Spirit, etc., etc., things essential to that Christianity by which the soul is saved, are ready to cry out, Thou art mad: he is an enthusiast: that is, a religious madman; one who is not worthy to be regarded; and yet, strange to tell, these very persons who thus cry out are surprised that Festus should have supposed that Paul was beside himself!
