Document Summary
Premise monotonicity: adding more facts should strengthen an argument . Dolphin cells contain th4 hormone, therefore cow cells contain th4 hormone which feels much weaker than this one: Note that this isn"t restricted to arguments that are explicitly written as syllogisms h. Dolphin cells contain th4 hormone, therefore cow cells contain th4 hormone o. The second argument feels a lot weaker than the original one, this is known as: Premise non-monotonicity: adding more examples weakens the strength of the. Dolphins and cows are dissimilar- it feels unreasonable to generalise from one to the o. Bats and mice are dissimilar to cows and dolphins- so when we add those to the argum feels like a stronger argument. The fact that the property (th4 hormone) is common to such a diverse set of an across mammals, so the generalisation to cows is sensible. Seals and whales are dissimilar to cows, but they are similar to dolphins.
