He is usually a sceptic, with a spontaneous interest in practical science.

But the theologian "intends" his mind away from practicalities and towards mysticism.

He is a professional believer in the supernatural; he discounts the value of merely "natural" phenomena.
His whole attitude of mind is unscientific; the fundamental tenets of his faith are based on alleged occurrences which inductive science cannot admit--namely, miracles.

And so the minds "intended" towards the supernatural achieved only the hazy mysticism of mediaeval thought.
Instead of investigating natural laws, they paid heed (as, for example, Thomas Aquinas does in his Summa Theologia) to the "acts of angels," the "speaking of angels," the "subordination of angels," the "deeds of guardian angels," and the like.

They disputed such important questions as, How many angels can stand upon the point of a needle?
They argued pro and con as to whether Christ were coeval with God, or whether he had been merely created "in the beginning," perhaps ages before the creation of the world.
