The necessity of pursuing true happiness is the foundation of all liberty- Happiness, in its full extent, is the utmost pleasure we are capable of.
John LockeAll men by nature are equal in that equal right that every man hath to his natural freedom, without being subjected to the will or authority of any other man; being all equal and independent, no one ought to harm another in his life, health, liberty or possessions.
John LockeError is none the better for being common, nor truth the worse for having lain neglected.
