In this essay I examine the contribution a philosophy of life is able to make to our understanding of morality, including our appreciation of its evolution or development and its future. I focus on two contributions, namely, those of Jean-Marie Guyau and Henri Bergson. In the case of Guyau I show that he pioneers the naturalistic study of morality through a conception of life; for him the moral progress of humanity is bound up with an increasing sociability, involving both the intensification of life and its expansion. In the case of Bergson I show that he also pioneers a novel naturalistic appreciation of morality, one that is keen to demonstrate morality's two sources and so as to give us a firm grasp of the chances of a moral progress on the part of humanity. I suggest that of the two appreciations of morality Bergson's is the richer since it contains a set of critical reflections on humanity's condition that is lacking in Guyau. I conclude by suggesting that Bergson's idea that modern humanity is confronted with the decision whether it wishes to continue living or not has lost none of its relevance today.
