The religion that is afraid of science dishonors God and commits suicide. Every influx of atheism, of skepticism, is thus made useful as a mercury pill assaulting and removing a diseased religion, and making way for truth.
How interesting it would be to write the story of the experiences in this life of a man who killed himself in his previous life; how he stumbles against the very demands which had offered themselves before, until he arrives at the realization that he must fulfill those demands. The deeds of the preceding life give direction to the present life.
When neither high purpose nor the categorical imperatives of religion will do, the only argument against suicide is life itself. You pause and attend: the heart beats in your chest; outside, the trees are thick with new leaves, a swallow dips over them, the light moves, people are going about their business.
The flip side of suicide is that it leaves a lingering question in the minds of the people who survived. Its like a cancer thats metastasized. The suicide is the cancer and the metastasis is all these people saying, Why? Why? Why?
