266. By subjecting all communications to a scrupulous examination, by scrutinizing and analyzing the thought and the expressions, as we should do were we judging a literary work, by unhesitatingly rejecting everything that sins against logic and good sense, everything that contradicts the character of the spirit reputed to be manifested; the deceiving spirits are discouraged, and end by withdrawing, once thoroughly convinced that they cannot deceive us. We repeat it, this is the only means, but it is infallible, because no bad communication can resist a rigorous criticism.
The good spirits are never offended by it, for they themselves advise it, and because they have nothing to fear from the examination ;• the bad alone take offence, and try to dissuade from it: this of itself proves what they are.
We give the advice of St. Louis on this subject: —
" However great may be the confidence with which the spirits who preside over your labors inspire you, it is a recommendation we cannot too often repeat, and which you should always bear in mind when you give yourself to your studies — to weigh and mature, that is, submit to the censorship of the severest reason, all the communications you receive ; as long as one point appears suspicious, doubtful, or obscure to you. not to neglect to ask the explanations necessary to satisfy you."
