Had you or I been born at the Bay of Soldania, possibly our Thoughts, and Notions, had not exceeded those brutish ones of the Hotentots that inhabit there: And had the Virginia King Apochancana, been educated in England, he had, perhaps been as knowing a Divine, and as good a Mathematician as any in it. The difference between him, and a more improved English-man, lying barely in this, That the exercise of his Facilities was bounded within the Ways, Modes, and Notions of his own Country, and never directed to any other or farther Enquiries.
John Locke[I]t being reasonable and just, I should have a right to destroy that which threatens me with destruction: for by the fundamental law of nature, man being to be preserved as much as possible, when all cannot be preserved, the safety of the innocent is to be preferred: and one may destroy a man who makes war upon him, or has discovered an enmity to his being, for the same reason that he may kill a Wolf or a lion.
John LockeAll the entertainment and talk of history is nothing almost but fighting and killing: and the honour and renown that is bestowed on conquerors (who for the most part are but the great butchers of mankind) farther mislead growing youth, who by this means come to think slaughter the laudable business of mankind, and the most heroic of virtues.
John Locke
