It is true that in the absence of a divine plan our lives have no externally determined purpose: an individual is not born for the purpose of becoming a physician or creating a spectacular work of art or digging a well in an arid corner of Africa. But are the sick less cured, the pleasure to the art-lover less intense, or the thirst of parched villagers less slaked, simply because a man sought his own purpose rather than following a diktat from on high? Do we really need a deity to tell us that a life spent curing cancer is more worthwhile than one spent drinking in the gutter?

Why should we not find satisfaction in alleviating suffering or injustice, just because we’re all going to die one day? The very fact that this life is all we have makes it even more important to do everything possible to reduce the suffering caused by poverty, disease, injustice and ignorance. To describe such attempts as meaningless is to say that avoidable suffering does not matter, hardly a moral stance.
