       | The same questions posed by "astronomical suffering" in this

       | The infamous (amongst academic philosophers) book _Better Never
       | to Have Been: The Harm of Coming into Existence_ [0] by David
       | Benatar, takes the stance that no it is not ethical to bring a
       | human into this world.

               | The absolutism and anthropocentrism inherent in that

               | indirect, but harm nonetheless.
               | 
               | Sure we should try to minimize the harm we cause others,
               | within reason, on a case-by-case basis, but if your best
               | solution to that is self-imposed specicide, what is the

           | It's basic question is "how shall I live?" It is concerned
           | with one's voluntary acts, which presupposes one's existence.
           | It is ridiculous to speak of one's _existence_ as being bad

           | others when you 've already undermined the value of the
           | existence of the individual. The measure of the moral life is
           | rooted in how well voluntary acts accord with human nature.
           | Immorality manifests in the discrepancy between nature and
           | voluntary act. If human beings were cannibals by nature,
           | there would be nothing wrong with cannibalism, for example,
           | because being a cannibal would advance the actualization of a
           | human individual and thus contribute to his good. But we
           | aren't, and because of our social nature, cannibalism is to
           | our own grave detriment in various ways. You cannot make such
           | moral judgements, or make sense of notions like
           | "selfishness", outside the context and parameters of the
           | social nature of human beings. What is good for human beings
           | is determined by our nature. And because of our social
           | nature, it is good that others exist.

               | going to think "hundreds of trillions" when someone says
               | "dozens". If one is expected to think "hundreds of

               | expected to think "hundreds of quadrillions" which would
               | be incorrect here.

               | Even if one agrees that "dozens" is accurate to mean
               | "hundreds of trillions" it still misses the mark for the
               | argument because the odds come from the high number of
               | planets. That is to say, there are very low odds that any
               | individual planet harbors life but ostensibly much
               | greater odds that one planet in a set of planets harbors
               | life. Saying "hundreds of trillions" gets that point
