Human Happiness Seems To Consist

..when, In My Philosophical Disquisitions, I Deny A Providence And A Future State, I Undermine Not The Foundations Of Society, But Advance Principles, Which They Themselves, Upon Their Own Topics, If They Argue Consistently, Must Allow To Be Solid And Satisfactory.

Nothing Is Pure And Entire Of A Piece. All Advantages Are Attended With Disadvantages. A Universal Compensation Prevails In All Conditions Of Being And Existence.

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.

We Have No Other Notion Of Cause And Effect, But That Of Certain Objects, Which Have Always Conjoin'd Together, And Which In All Past Instances Have Been Found Inseparable. We Cannot Penetrate Into The Reason Of The Conjunction. We Only Observe The Thing Itself, And Always Find That From The Constant Conjunction The Objects Acquire An Union In The Imagination.

What Is Easy And Obvious Is Never Valued; And Even What Is In Itself Difficult, If We Come To Knowledge Of It Without Difficulty, And Without And Stretch Of Thought Or Judgment, Is But Little Regarded.
