2849. In the world also, or their life of the body, the deceitful are distinguished, although they are not discriminated by men. For certain, from implanted habit [consuetudine] and actuality do not premeditate deceits, but wherever occasion is offered, bring about results [exercent effectus] in a deceitful manner; therefore, not in so premeditated a manner. Such are [they] who are tolerated, for their nature is known. But there are those in the world, who premeditate, and hide their deceits in the mind [animo] and wear a friendly countenance, but still meditate under a friendly countenance occasions to hurt, and this a long time. These are they who are not tolerated, and are vipers [cerpentes viperae]. [I spoke] of these, with spirits: for a certain one injured [hurt] me very slightly; but inasmuch as he was of such a character, as to act too from instinct; therefore a handle [an opportunity] was given me to think and speak concerning these things. - 1748, August 17.
