Fermi's Paradox: Are We Alone?



Does Fermi's paradox make a case for the proposition that we are in fact alone, that there are no other intelligences in the universe?

I attended Enrico Fermi High School in a suburban town where the high school got that name because there were a lot of Italian-Americans in town, and this seemed to some politician a nice sop to them.

The story is that Fermi originally raised the issue now called his "paradox" in a conversation with other physicists in 1950, at a time when there were lots of reports of flying saucer sightings in the newspapers. The smart people around the lunch table, Manhattan Project veterans all of them, believed intelligent life elsewhere was probable, though they disbelieved in the idea that the smudgy photographs supposedly showing "saucers" in the air had anything to do with it.

The conversation had moved on to other subjects, but Fermi brought it back to that one, blurting out after a period of meditative silence: "but then where is everybody?"

If you believe that we are not unique, then you are right to wonder why we haven't been contacted.

The paradox has gotten sharper over the decades. Heck, we've had television broadcasts since around the time of that conversation. Somebody in outer space 70 light years away may be enjoying "I Love Lucy" right now.  If somebody 35 light years away received those signals in 1985 and replied immediately we'd be receiving that response now.

Where, indeed, IS everybody?

See my comment on the movie AD ASTRA last week.

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.   We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a majesti

Five Lessons from the Allegory of the Cave

  Please correct me if there are others. But it seems to be there are five lessons the reader is meant to draw from the story about the cave.   First, Plato  is working to devalue what we would call empiricism. He is saying that keeping track of the shadows on the cave wall, trying to make sense of what you see there, will NOT get you to wisdom. Second, Plato is contending that reality comes in levels. The shadows on the wall are illusions. The solid objects being passed around behind my back are more real than their shadows are. BUT … the world outside the the cave is more real than that — and the sun by which that world is illuminated is the top of the hierarchy. So there isn’t a binary choice of real/unreal. There are levels. Third, he equates realness with knowability.  I  only have opinions about the shadows. Could I turn around, I could have at least the glimmerings of knowledge. Could I get outside the cave, I would really Know. Fourth, the parable assigns a task to philosophers

Searle: The Chinese Room

John Searle has become the object of accusations of improper conduct. These accusations even have some people in the world of academic philosophy saying that instructors in that world should try to avoid teaching Searle's views. That is an odd contention, and has given rise to heated exchanges in certain corners of the blogosphere.  At Leiter Reports, I encountered a comment from someone describing himself as "grad student drop out." GSDO said: " This is a side question (and not at all an attempt to answer the question BL posed): How important is John Searle's work? Are people still working on speech act theory or is that just another dead end in the history of 20th century philosophy? My impression is that his reputation is somewhat inflated from all of his speaking engagements and NYRoB reviews. The Chinese room argument is a classic, but is there much more to his work than that?" I took it upon myself to answer that on LR. But here I'll tak
