As therefore the highest perfection of intellectual nature lies in a careful and constant pursuit of true and solid happiness, so the care of ourselves, that we mistake not imaginary for real happiness, is the necessary foundation of our liberty. The stronger [the] ties we have to an unalterable pursuit of happiness in general . . . the more are we free from [obedience to an immediate impulse for some pleasure]. –“An Essay Concerning Human Understanding,”

John Locke, 1690
