It sort of looks that way if you read him as straightforwardly stating facts, but I think he’s really written a bit of poetic prose there - not intended to bring people to a factual understanding of what suicide is, but intended to inspire people to think differently about what it means to be alive.
I think the world is overpopulated…and I want to reserve voluntary suicide for people who are not mentally ill.
Mental illness, the usual cause of suicide, undermines the validity of the decision. It’s a bad decision, just as decisions often are when made while one is angry, or has just broken up with a former lover, or is drunk.
If someone who is rational and sane and competent to make a decision, a legal adult, and not under any form of coercion, chooses suicide, what basis do we have to stop him? We don’t stop people from taking risks with their lives; why should we stop them from throwing their lives away entirely?
Why don’t we compel people to stop smoking? That’s only slow-motion suicide.
I think that if Chesterton had lived to see it, he would have made fun of that failed doomsday prophecy, and many others as well.
“Every so often, a new sect appears, enthusiastically spreading the news that the world will soon end. By a slight error of calculation, it is usually the sect that soon ends.” - G. K. Chesterton
