Action is the activity of the rational soul, which abhors irrationality and must combat it or be corrupted by it. When it sees the irrationality of others, it must seek to correct it, and can do this either by teaching or engaging in public affairs itself, correcting through its practice. And the purpose of action is to enable philosophy to continue, for if men are reduced to the material alone, they become no more than beasts.
[..] intelligent people only have a certain amount of time (measured in subjective time spent thinking about religion) to become atheists. After a certain point, if you're smart, have spent time thinking about and defending your religion, and still haven't escaped the grip of Dark Side Epistemology, the inside of your mind ends up as an Escher painting.
For, from the time that the Bishop of Rome had gotten to be acknowledged for bishop universal, by pretence of succession to St. Peter, their whole hierarchy, or kingdom of darkness, may be compared not unfitly to the kingdom of fairies; that is, to the old wives' fables in England concerning ghosts and spirits, and the feats they play in the night. And if a man consider the original of this great ecclesiastical dominion, he will easily perceive that the papacy is no other than the ghost of the deceased Roman Empire, sitting crowned upon the grave thereof: for so did the papacy start up on a sudden out of the ruins of that heathen power.
The practice which obtains amongst the Americans of fixing the standard of their judgment in themselves alone, leads them to other habits of mind. As they perceive that they succeed in resolving without assistance all the little difficulties which their practical life presents, they readily conclude that everything in the world may be explained, and that nothing in it transcends the limits of the understanding. Thus they fall to denying what they cannot comprehend; which leaves them but little faith for whatever is extraordinary, and an almost insurmountable distaste for whatever is supernatural.
Considering he was neither priest nor scholar, the young man gave sensible, thoughtful replies -- the more so, perhaps, for being untrained, for he had not learned what he should believe or should not believe. Present a statement to him in flagrant contradiction to all Christian doctrine and he could be persuaded to agree on its good sense, unless he remembered it was the sort of thing of which pyres are made for the incautious.
