Now the spirit in question cannot be a demon: you own that instead of inspiring you anything contrary to piety and religion, he often fortifies in you the maxims of Christianity: he strengthens your faith by profound reasonings, and has the same respect with you for sacred names and things. Neither can you say that it is an angel; for though you have always led a regular life, and far from all dissoluteness; though for some years past you have applied yourself, after a particular manner, to the duties of a true Christian, you will agree with me, that these sorts of favours are not common; that a man must have attained to a high degree of sanctity, and not be far from the pureness of celestial spirits, to merit a familiar converse, and bear a harmony with them. Believe me, there is nothing in all these discourses which you imagine you have with this spirit. You know, better than any man, those symptoms which the black humours wherewith you are tormented causes in you. Your vapours are the source of your visions, and yourself would not judge otherwise of another person to whom a like thing should happen; and you will come to this in your own respect also, if you will make a mature reflection, and apply yourself to blot out, by an effort of reason, these imaginations which the violence of your evil effect causes in you. You may have reason, replied Tasso, to think so of the things that pass in me; but as to myself, who have a sensible perception of them, I am forced to reason after another manner. If it were true that the spirit did not show himself to me, but in the violent assault of my vapours; if he offered to my imagination but wandering and confused species, without connection or due sequel; if he used to me frivolous reasonings, which ended in nothing; or if having begun some solid reasoning he broke it off on a sudden, and left me in darkness, I should believe with you, that all things that pass are but mere dreams and phantoms; but it is quite otherwise. This spirit is a spirit of truth and reason, and of a truth so distinct, of a reason so sublime, that he raises me often to knowledges that are above all my reasonings, though they appear to me no less clear; that he teaches me things which, in my most profound meditations, never came into my spirit, and which I never heard of any man, nor read in any book. This spirit, therefore, is somewhat of real; of whatsoever order he be, I hear him and see him, nevertheless for its being impossible for me to comprehend and define him. Manso did not yield to these facts, which Tasso would have passed for proofs; he pressed him with new questions, which were not without answers. Since you will not believe me on my word, said Tasso to him another day, after having well disputed, I must convince you by your own eyes, that these things are not pure imaginations: and the next day, conversing together in the same chamber, Manso perceived that, on a
