Have you, by chance, read An Essay Concerning Human Understanding?
"I have always thought the actions of men the best interpreters of their thoughts."
It is interesting how some things seem to hold true regardless of whether one is human or something else, don't you think? Surely you of all people must have encountered it plenty? Human sinners claiming innocence, claiming good intent whilst their actions speak volumes of their true character?
I have seen it countless times myself: people professing to care for their fellow man; for their family and relatives; wishing to aid them in their darkest moments, and yet they do nothing. Is that not telling?
