That does not logically follow. If that a new invention, is the result of logic and reason, that doesn't mean that being logical and reasonable at a certain level is enough. For instance an extreme amount of logic and reason is necessary to result in the building of a computer from scratch. A very extreme amount of logic and reason is necessary to build an invention that will grant immortality. Incorrect. We are the dominant species because we are cautious and predict patterns. Lemmings are not afraid of the unknown and look where that got them. There is every reason to logically fear death, even if that is an emotionless fear of pure logic, because you do not know where or what you shall end up. This is one of the reasons I am against religion, because it teaches people that they have no need to fear the unknown, that they should simply have faith in god.
