And if there were nothing else that bewrayed their madnesse; yet that very arrogating such inspiration to themselves, is argument enough.

If some man in Bedlam should entertaine you with sober discourse; and you desire in taking leave, to know what he were, that you might another time requite his civility; and he should tell you, he were God the Father; I think you need expect no extravagant action for argument of his Madnesse.
This opinion of Inspiration, called commonly, Private Spirit, begins very often, from some lucky finding of an Errour generally held by others; and not knowing, or not remembring, by what conduct of reason, they came to so singular a truth, (as they think it, though it be many times an untruth they light on,) they presently admire themselves; as being in the speciall grace of God Almighty, who hath revealed the same to them supernaturally, by his Spirit.
Again, that Madnesse is nothing else, but too much appearing Passion, may be gathered out of the effects of Wine, which are the same with those of the evill disposition of the organs.

For the variety of behaviour in men that have drunk too much, is the same with that of Mad-men: some of them Raging, others Loving, others laughing, all extravagantly, but according to their severall domineering Passions: For the effect of the wine, does but remove Dissimulation; and take from them the sight of the deformity of their Passions.

For, (I believe) the most sober men, when they walk alone without care and employment of the mind, would be unwilling the vanity and Extravagance of their thoughts at that time should be publiquely seen: which is a confession, that Passions unguided, are for the most part meere Madnesse.
The opinions of the world, both in antient and later ages, concerning the cause of madnesse, have been two.

Some, deriving them from the Passions; some, from Daemons, or Spirits, either good, or bad, which they thought might enter into a man, possesse him, and move his organs is such strange, and uncouth manner, as mad-men use to do.
