"Explaining why induction commonly works has been somewhat problematic. One cannot use deduction, the usual process of moving logically from premise to conclusion, because there is simply no syllogism that will allow such a move. No matter how many times 17th century biologists observed white swans, and in how many different locations, there is no deductive path that can lead them to the conclusion that all swans are white."
