I honestly half expected to see him on the page of saints already, but alas only Darwin was there. In many ways, he could be considered a godfather of memetic thought, for he thought of ideas as having evolved to fill a specific niche in the human psyche. In "On the Genealogy of Morals" he examined (among other things) exactly this, if only one specific case of it.

He's all but quoted in your explanation of dogmatism as a sin. Compare your "Convictions...are the enemy of truth more than lies" to his "Convictions are more dangerous enemies of truth than lies." One could say that he was the first to define dogmatism as a sin, as something not to be desired but rather detested.
