The sum total of happiness and misery in this world is at least the same throughout. If a wave rises in the ocean it makes a hollow somewhere. If happiness comes to one man, unhappiness comes to another or, perhaps, to some animal. Men are increasing in numbers and some animals are decreasing; we are killing them off, and taking their land ; we are taking all means of sustenance from them. How can we say, then, that happiness is increasing? The strong race eats up the weaker, but do you think that the strong race will be very happy? No; they will begin to kill each other. I do not see on practical grounds how this world can become a heaven. Facts are against it. On theoretical grounds also, I see it cannot be.
