      Project Astrolabe Retweeted Daniel Fischer

      It is interesting to note in this context that Freeman Dyson also identified SETI assumptions that he called the "Philosophical Discourse Dogma," though Dyson's concerns were a bit different from those of Kelvin Long. Disturbing the Universe, III, 19. "Extraterrestrials," p. 207https://twitter.com/cosmos4u/status/1093169558406475776 …

      Project Astrolabe added,

      Daniel Fischer @cosmos4u
      Have questionable assumptions "guided the SETI community towards a constrained level of thinking that is equivalent to philosophical dogma"? First the paper https://arxiv.org/abs/1901.10551 , then the thread https://twitter.com/Astro_Wright/status/1090995609413267457 … - and now https://twitter.com/IcarusAstrolabe/status/1093035884931215360 … (still no ET call, BTW).

      Dyson was responding to Edward Purcell, who had written of SETI: “It is a conversation which is, in the deepest sense, utterly benign... Here one has the ultimate in philosophical discourse—all you can do is exchange ideas, but you can do that to your heart’s content.”

      Dyson's Philosophical Discourse Dogma has three theses: 1. Life is abundant in the universe. 2. A significant fraction of the planets on which life exists give rise to intelligent species. 3. A significant fraction of intelligent species transmit messages for our enlightenment.

      Dyson's first and second theses are shared with the Fermi paradox (if we were to lay it out as systematically). We could break 3. into two parts: 3a. intelligent species transmit messages, or 3b. intelligent species travel to other worlds, & 3rd thesis is also the Fermi paradox.

      But in acknowledging the multiple pathways by which an intelligent species might make itself known in the cosmos we break with the essence of the Philosophical Discourse Dogma, because the local presence of an intelligent species may not be benign.

      Replying to @IcarusAstrolabe

      Astronomical evidence tells us beyond all reasonable doubt that ETI are at best very rare. Listening to a popular 20th century medium (radio) emanating from our own galaxy is like listening with tin cup for a California Condor in your own back yard.
