In nature all animals 1mg finpecia fast delivery, including hum an beings generic 1mg finpecia mastercard, survive on the basis of principles of natural selection. N ature “chooses” from a “blooming profu sion” of choices those life forms with survival value. One species of moth survives because a random m utation in the coloration of its wings happily blends into the field of flora in which it lives; another is decimated by predators because its wing color ation contrasts rather than merges with the backdrop. His reasoning runs som ething like this: If there are unmistak able signs of decay in our culture—the population explosion (upon which he relies heavily), environm ental degrada tion, wide-ranging mental instability, endless war and conflict—then for that culture to survive, it must evolve. In short, according to Salk, it must reestablish a harmonious relationship with its surroundings. But this can only take place through natural selection; nature will judge us for our survival value. Salk argues that we must therefore create and then share ideas that have survival value. What is novel about Salk’s thinking is that it can now be made public by such a distinguished scientist and scholar. Those who argue that hu An Emerging Zeitgeist 145 manity has reached an epoch break, a point of transition to a new era and a new humanity, are not lonely voices in the wilderness but part of a growing chorus. T he first, which foresees the end of civilization, the dissolution of culture, is well represented by Lewis M um ford in The Myth of the Machine, by William Irwin Thom pson in At the Edge of History and Passages About Earth, and by George Leonard. Some o f these commentators, such as Leonard, have gone on to the second argum ent—that a new epoch is em erging, or at least that we are on its threshold. It has become less and less easy to dismiss these voices as millenarian, rustic, nonscientific, or even crazy. Sociocultural innovation is impoverished, and economic and political structures are variations on a common and empty theme. Revolutions and revolts, each chasing on the heels o f its predecessor, disap pear one into another in a dreary uniform ity—the op pressed become the oppressors, and so on. In The Struggle Against History, Ronald Segal, a socialist critic and writer, recognizes this when he says of the two dom inant political and economic systems: “While the two.
