[the Sceptic] Must Acknowledge, If He Will

...virtue Is Attended By More Peace Of Mind Than Vice, And Meets With A More Favourable Reception From The World. I Am Sensible, That, According To The Past Experience Of Mankind, Friendship Is The Chief Joy Of Human Life And Moderation The Only Source Of Tranquillity And Happiness.

I Say Then, That Belief Is Nothing But A More Vivid, Lively, Forcible, Firm, Steady Conception Of An Object, Than What The Imagination Alone Is Ever Able To Attain. This Variety Of Terms, Which May Seem So Unphilosophical, Is Intended Only To Express That Act Of The Mind, Which Renders Realities, Or What Is Taken For Such, More Present To Us Than Fictions, Causes Them To Weigh More In The Thought, And Gives Them A Superior Influence On The Passions And Imagination.

Moving From An Objective Statement Of Fact To A Subjective Statement Of Value Does Not Work, Because It Leaves Open Questions That Have Not Been Answered.

If Morality Had Naturally No Influence On Human Passions And Actions, It Were In Vain To Take Such Pains To Inculcate It; And Nothing Would Be More Fruitless Than That Multitude Of Rules And Precepts With Which All Moralists Abound.

It Is Not Reason Which Is The Guide Of Life, But Custom.
