Document Summary
Main argument: there is no good reason to think that in the future objects will have the same properties they did in the past (against common sense) Demonstrative reasoning: has to do with relationships between ideas: has to do with logic of our concepts, examples: 2+2=4. Moral reasoning: has to do with matters of fact and what exists: depends on having certain experiences (beyond what you need to get the concept itself, examples: today is monday. Recall: demonstrative reasons are reasons that turn on relations between ideas. I. e. they are things that are true merely because of the concepts involved. They are the kinds of things you can know merely by understanding the concepts. Examples: 2+2=4, red is a color, all bachelors are unmarried. Recall: moral reasons are reasons that turn on matters of fact. I. e. they are things that are not true merely because of the concepts involved.
