The right to life means that a man has the right to support his life by his own work (on any economic level, as high as his ability will carry him); it does not mean that others must provide him with the necessities of life.
A “right” is a moral principle defining and sanctioning a man’s freedom of action in a social context. There is only one fundamental right (all the others are its consequences or corollaries): a man’s right to his own life. Life is a process of self-sustaining and self-generated action; the right to life means the right to engage in self-sustaining and self-generated action — which means: the freedom to take all the actions required by the nature of a rational being for the support, the furtherance, the fulfillment and the enjoyment of his own life. (Such is the meaning of the right to life, liberty and the pursuit of happiness.)
