Thirty-seventh in a series of notes and comments on The Book of Barely Imagined Beings
Chapter 27: Zebrafish
page 374: singularity. Gary Marcus critiques Ray Kurzweil's theory of mind and argues artificial intelligence has some way to go. Evan Goldstein has looked at the strange neuroscience of immortality in some depth. Max Tegmark says:
[the singularity] could be the best or worst thing ever to happen to life as we know it, so if there's even a 1% chance that there'll be a singularity in our lifetime, I think a reasonable precaution would be to spend at least 1% of our GDP studying the issue and deciding what to do about it. Yet we largely ignore it, and are curiously complacent about life as we know it getting transformed. What we should be worried about is that we're not worried.page 374: play. Attributed to Heraclitus:"We are most nearly ourselves when we achieve the seriousness of the child at play." In the final chapter of Religion in Human Evolution, Robert Bellah quotes from Friedrich Schiller's On the Aesthetic Education of Man:
Certainly nature has given even to the creatures without reason more than the bare necessities of life, and cast a gleam of freedom over the darkness of animal existence. When a lion is not gnawed by hunger and no beast is challenging him to battle, his idle energy creates for itself an object; he fills the echoing desert with his high-spirited roaring, and his exuberant power enjoys itself in purposeless display...The animal works when deprivation is the mainspring of its activity, and it plays when the fullness of its strength is the mainspring, when superabundant life is its own stimulus to activity.Schiller -- notes Bellah -- contrasts “the sanction of need, or physical seriousness” with the “sanction of superfluity, or physical play,” but suggests that human play, though beginning in physical play, can move to a level of aesthetic play in which the full spiritual and cultural capacities of humans can be given free reign:
Man plays only when he is in the full sense of the word a Man, and he is only wholly Man when he is playing.Also of note is what Schiller says about play and time:
The sense impulse requires variation, requires time to have a content; the form impulse requires the extinction of time, and no variation, Therefore the impulse in which both are combined (allow me to call it provisionally the play impulse), this play impulse would aim at the extinction in time and the reconciliation of becoming with absolute being, of variation with identity.(Added 30 Jan: Play not work brings us fully to life, says Mark Rowlands)
