state of war is a state of enmity and destruction: and therefore declaring by word or action, not a passionate and hasty, but a sedate settled design upon another man's life, puts him in a state of war with him against whom he has declared such an intention, and so has exposed his life to the other's power to be taken away by him, or any one that joins with him in his defence, and espouses his quarrel; it 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; because such men are not under the ties of the commonlaw of reason, have no other rule, but that of force and violence, and so may be treated as beasts of prey, those dangerous and noxious creatures, that will be sure to destroy him whenever he falls into their power.
