An indifferent sense
Others take the word in an indifferent sense, such as is neither morally good nor evil. Thus they speak of the enthusiasm of the poets, of Homer and Virgil in particular. And this a late eminent writer extends so far as to assert that there is no man excellent in his profession, whatever it is, who does not have in his temper a strong tincture of enthusiasm. By enthusiasm these appear to understand an uncommon vigor of thought, a peculiar fervor of spirit, a vivacity and strength not to be found in common men, elevating the soul to greater and higher things than cool reason could have attained.

9. Others take the word in an indifferent sense, such as is neither morally good nor evil. Thus they speak of the Enthusiasm of the poets; of Homer and Virgil in particular. And this a late eminent writer extends so far as to assert, there is no man excellent in his profession, whatsoever it be, who has not in his temper a strong tincture of Enthusiasm. By Enthusiasm these appear to understand, an uncommon vigour of thought, a peculiar fervor of spirit, a vivacity and strength not to be found in common men: elevating the soul to greater and higher things, than cool reason could have attained.
