Long before the "me too" movement, Beelzebub wrote a book called I Too
Speaking of the Devil and good grammar, Fernando Pessoa included this marvelous passage in his Book of Disquiet.
He refers to occult writers:
What really shocks me is how these wizards and masters of the invisible, when they write to communicate or intimate their mysteries, all write abominably. It offends my intelligence that a man can master the Devil without being able to master the Portuguese language. Why should dealing with demons be easier than dealing with grammar? If through long exercises of concentration and will power one can have so-called astral visions, why can’t the same person — applying considerably less concentration and willpower — have a vision of syntax? What is there in the teachings and rituals of the Magic Arts that prevents their adherents from writing — I won’t say with clarity, since obscurity may be part of the occult law — but at least with elegance and fluency, which can exist in the sphere of the abstruse? Why should all the soul’s energy be spent studying the language of the Gods, without a pittance left over to study the colour and rhythm of the language of men?
