Ovulation Quotes

We inhabit a complex world. Some boundaries are sharp and permit clean and definite distinctions. But nature also includes continua that cannot be neatly parceled into two piles of unambiguous yeses and noes. Biologists have rejected, as fatally flawed in principle, all attempts by anti-abortionists to define an unambiguous "beginning of life,” because we know so well that the sequence from ovulation or spermatogenesis to birth is an unbreakable continuum-and surely no one will define masturbation as murder. (Stephen Jay Gould)
