I don't have a problem with Carl Sagan's criticism of superstitions and other irrational beliefs. But to attack them with skepticism and at the same time believe in aliens, flying saucers and ETI is a contradiction.
There are several instances in his biography that demonstrates how seriously he took aliens and UFOs. He even wrote to the Sectary of State wanting to know if the US was prepared for an alien attack. He did turn skeptical of UFOs later on. But that did not stop him from dedicating his whole life to search for alien life after he denounced them. I am sure there are many scientist also keen on looking for aliens, UFOs. But how does a rational person like Carl Sagan dismiss people looking for aliens, UFOs HERE as wacky but still believe in a project looking for them in outer space (for 50 years). |

Seeking evidence is not "obsession", nor did Sagan limit his activities in those 50 years to efforts to collect that evidence.
But let's grant that he was obsessed, just for the sake of discussion. Carl Sagan was obsessed with finding evidence for ETI. And...? So...? How would that disqualify him from being a skeptic? |

No. You clearly have not read Sagan. He clearly stated that it was entirely possible that no signals would be detected, even after an exhaustive search. While this would not necessarily rule out the possibility of extraterrestrial civilizations, it would certainly give us empirical data that would allow us to narrow our speculations. Sagan specifically stated that hearing nothing but the cosmic noise of nature in our little part of the universe could suggest something of the rarity and preciousness of life.
The histrionic application of words like "obsession" and the use of emoticons do nothing but reveal your lack of an argument and your biases. Sagan did a great many things during his career, including working on projects that explored the other worlds in our solar system up close for the first time. SETI was certainly of interest to him, but it was, at best, a side project for him. I see no justification for your characterization of "obsession". |

You seem to be suggesting that a "rational person", or "skeptic", should reject the idea of alien life without bothering trying to find out if there is any evidence for it. Since "closed-mindedness" is a frequent criticism (unfairly) aimed at skeptics, it looks rather as if you're trying to erect a strawman argument. |

More importantly, from a scientific perspective, he made clear that any answer is the right answer. There is no "failure" if no signals are detected. The goal of the project is to investigate the true nature of the universe. If nothing is detected, then we know something about the nature of the universe (or at least our little part of it) that we did not know before. It doesn't tell us that we are alone as a civilization, but it does tell us that no one is sending signals using radiation. This could be because most civilizations quickly discover far better technologies than radio. Or it could be because civilizations don't last long enough to be around to communicate with others. Or it could be that we are an incredibly rare phenomenon in the galaxy, or even the universe. These are all questions worth seeking the answers to. But in order to seek those answers we have to start looking.

There are several factual problems with your claim here, as there have been every other time you have made it. I encourage you to provide evidence for the claims you make, as, after all, pursuing, and evaluating, evidence is one of the driving forces of skeptical inquiry.
1. Please provide evidence that Dr. Sagan "belkeived in" "aliens" (As opposed to, say, "searching for evidence of extraterrestrial intelligences"). 2. Please provide evidence that Dr. Sagan "beleived in" "UFOs", particularly given his work in debunking credulous claims of "UFO sightings" and "alien abductions". 3. Please provide evidence that Dr. Sagan "believed in" extra-terrestrial intelligences (as opposed to searching for evidence of extra-terrestrial intelligences). 4. Please explain how, on the one hand, explaining the superstitious nature of "UFO sightings" and "alien abduction" stories, based primarily upon the grounds that there is no evidence that UFOs have ever been sighted, or that anyone has ever been abducted by an "alien"; but looking for evidence of the existence of extra-terrestrial intelligences (instead of simply existing that they do, in fact, exist) is a "contradiction". As has been explained to you before, the letter you like to mention was written by a young man. In the letter, he did not say, "Since aliens exist, we must prepare", but instead, asked the Secretary of State (Dean Acheson, at the time) how the United States would respond if "UFOs" actually did turn out to be of extraterrestrial origin. You might want to consider re=reading the letter before claiming that it demonstrates that the young Sagan "believed in" "UFOs and aliens". As has been explained to you, the difference between. on the one hand, credulous claims of "UFOs" and "alien abductions" with no evidence (ever wonder why UFOs and aliens seem to bollix cameras and vidcorders at will?); and, on the other hand, searches for evidence of intelligent signals from outer space, or evidence of how "aliens" could abduct humans and leave no traces, or evidence of the existence of (and the physics that would allow) "flying saucers" is the difference between superstition and science; between knowing and believing. |

Sagan used the odds. He knew that there were ,as he's so often quoted, billions and billions of stars, if only a tiny amount supported planets, and of these planets only a tiny amount had liquid water, well by golly there "could' be life there. and if only one other watery world had evolved intelligent life, well it's our duty as another intelligent species to seek them out!!
Trying to besmirch the character of Sagan due to some hidden agenda on your part is cute. But it isn't gonna work. Not that way anyway, I would refer you to the kiddy pool, but apparently you got banned from there. This is the grownups area, and yer gonna have to do better than that. |

Going looking for them is looking for the evidence. That's what you do before you claim something exists, not after.
Sagan thought it was possible intelligent life lived on other planets and used radio waves to communicate. Obviously this is possible, since we already know of one planet where intelligent organisms use radio waves to communicate. |

Are you able to comprehend that someone can look for something without having a positive belief that it exists? You've already attempted to use innocence until proof of guilt as an analogy in another thread. Can you understand that a juror can look for evidence of someone's guilt without having positive belief in the person's guilt? Sagan, and many other scientists, thought/think that it is possible that life has evolved on other worlds, and that some of this life may have evolved the intelligence to generate radio signals. They do not claim that this is a fact. It is a possibility that is being investigated.
By the way, as has already been pointed out to you, Carl Sagan did not regard UFOs as evidence of alien life. He regarded them as evidence of certain aspects of human imagination and the unreliability of human perception.
Quote:
He skeptically investigated the idea of UFOs and found no credible evidence for their reality, as well as a lot of credible evidence from the fields of psychology and sociology to explain why people believed they saw them or their crews. He did not claim that alien life or alien civilizations exist. He only noted the possibility and, like a scientist, began investigating the matter to determine if such life can be detected.
Quote:
Ironically, had he dismissed the possibility of life elsewhere in the universe simply because UFO claims have proved unconvincing, he'd have been guilty of the same sort of closed-mindedness that you are generically accusing skeptics of. |

Um so how that make him not a skeptic? Life and intelligent life existing elsewhere in the universe is a statistical given, as improbable as it may be that we will meet them it is not irrational to search for it and hope you may find evidence. Personally I hope and cross my fingers that they will figure out ageing in my lifetime, but they probably wont and if they do I probably wont be able to make use of it.

Your logic is totally flawed.
1. If he did not think aliens were a threat why did he write to the Sectary of State concerned if they were prepared for an alien attack. In fact he is not alone in thinking aliens are threatening. Stephen Hawkins is another scientist who warns of making contact with aliens because they might not have altruistic intentions. 2. Nothing has been explained to me. You are the one asking the questions. 3. It is dumb to say he was looking for the evidence of ETI but did not believe in them. In fact you got it backwards. He had to know what he was looking for. He had to tell people who were funding him what he was looking for and also convince them of the chance/probability of finding them after he convinced himself. He had to make them believe they exists. All this even before he started looking for them or as you like to say evidence of them. The evidence of ETI would go a long way to validate his beliefs and convictions of their existence. Just like the results of a scientific research can confirm or invalidate the hypothesis. |

There is evidence that expressing disdain for skeptics and contempt for skepticism is the point. At least that's one possibility suggested by the OP's history of being banned from other skeptics' forums for expressing that disdain and contempt while failing to provide any rationale for it. |

Clearly you take exception to the fact that many people here do not believe something you believe in. Would you care to share what it is that you believe in that you think we should? As you posted this in Religion and Philosophy I have a pretty good idea what it was but I won't put words in your mouth.

BTW, Sagan was 17 when he wrote that letter to the DOD about aliens. But you probably knew that and hoped we wouldn't....
He stated clearly that he found it very possible for ETI to exist, but he did not say that he "believed hey existed". He clearly states in one of his books that he thinks that UFO's were a construct of The Cold War, and that both sides used this fear as a tool of propaganda. so, in other words, you have nothing but accusations, and no evidence to back it up. (except trying to wash over an esteemed scientists entire career with the fact that when he was 17 he was interested in UFOs enough to write a letter to the Gubbmint.) |

I have another OP Is scientific skepticism really rationalism. The whole exercise is to question the examples Skeptics use as Skeptic advocates. Is Skepticism a philosophical approach or a state of mind (psychological)? Carl Sagan preached scientific skepticism which appears to deviate from philosophical skepticism, but is that just a repackaging of rationalism. Because again going back to the definitions:
Skepticism: 1. A doubting or questioning attitude or state of mind; dubiety synonyms with uncertainty. |

And he also wrote Contact which was all about UFOs, alien spacecraft and alien encounters. Here he is pandering to the so called irrational and trying to profit from it after he claimed to be a Skeptic of UFOs. It is hard to be a scientist and not indulge in some wild speculations or vicariously live in fiction, what the real world cannot provide, except in fantasy land.
