“There is no method of reasoning more common, and yet none more blameable, than, in philosophical disputes, to endeavour the refutation of any hypothesis, by a pretence of its dangerous consequences to religion and morality. When any opinion leads to absurdities, it is certainly false; but it is not certain that an opinion is false, because it is of danger-ous consequence. Such topics, therefore, ought entirely to be forborne; as serving nothing to the discovery of truth, but only to make the personof an antagonist odious.”

“When principles are so absurd and so destructive of human society, it may safely be averred, that the more sincere and the more disinterested they are, they only become the more ridiculous and the more odious.”

“Be a philosopher, but amid all your philosophy be still a man.”

“Be a philosopher; but, amidst all your philosophy, be still a man.”

“[T]he Old Testament, [...] if considered as a general rule of conduct, would lead to consequences destructive of all principles of humanity and morality.”

“If my life be not my own, it were criminal for me to put it in danger, as well as to dispose of it; nor could one man deserve the appellation of hero, whom glory or friendship transports into the greatest dangers, and another merit the reproach of wretch or misereant who puts a period to his life, from the same or like motives.”
