Persuasion (n.) and conviction differ not in degree but in kind.
Persuasion (n.) in religion produces a beneficent illusion that abhors logical criticism as if it sprang from impious misgiving.
Persuasion (n.) may be kept for oneself if one pleases, but one cannot and should not want to make it valid beyond oneself.
Persuasion (n.) never quite rids us of the lurking suspicion that we are being artfully hoodwinked, being as ready to cloak vice and error as to serve truth.
Persuasion (n.) is a mere semblance of conviction: its ground lies only in the subject but is mistaken for objective, so it has merely private validity and cannot be communicated.
