This is our freshly minted little girl. The physical manifestation of our evolutionary drives. We think she is beautiful, but we would, wouldn't we? Evolution sees to that. And evolution, often through concealed agency, sees to it that we express, or attempt to enhance, our social status by communicating our great good fortune at having a healthy by-product of our pair-bonding, and of our love. I could shout it from the rafters, or hand out cigars, but a blog should do the job.
Peter Singer recently published The Most Good You Can Do, wherein he advocates effective altruism, the idea that it is incumbent on all of us (at least anyone with the opportunity to read a blog) to live inexpensively, and to benefact causes that spend the donations in ways calculated to do the most good.
