John B. S. Haldane

We can, for example, be fairly confident that either there will be a world without war or there won't be a world - at least, a world inhabited by creatures other than bacteria and beetles, with some scattering of others.

Some people conclude that the injustices existing in the world prove there is no God. On the contrary, I conclude that God, being both just and merciful, will and can rectify all inequities in a life after death.
