Presidentti Lincoln päätti hyökätä

"kävimme jo tämän keskustelun vuosi sitten ennen kuin haihduit savuna ilmaan"

Puhumattakaan anonyymin pirinvetelijäneron aivoituksesta laittaa niinkin idioottimainen viallinen analogia kuin verrata Lincolnia Vladimir Putiniin. Ei taida olla ihan laillisia neron vetelemät aineet.

》A false or faulty analogy consists of assuming that because two or more things are similar in one way, then they are also similar in some other way, ignoring any important distinctions between the two.

》One might say that the protein complex that moves the flagellum of a bacterium is like a motor. Creationists then argue that this is evidence against evolution, because motors are designed and therefore the flagellum must also have been designed. They are taking a metaphor that was intended to convey one meaning and extending it to another, turning a legitimate analogy into a false analogy. Flagella are like motors in that they have multiple moving parts that work together to create a specific motion. This is where the analogy ends, however. The flagellum is a biological motor, so it has a biological origin. Car motors are not biological; they are inanimate and therefore cannot evolve on their own.

》False analogy can be a very subtle logical fallacy. You must always ask the question: Are the things being compared truly analogous, and even if they are analogous in some ways, are they analogous in the specific ways that are being claimed?《
