1. Philosophy / D. Nature of Philosophy / 2. Invocation to Philosophy
All other human gifts can harm us, but not correct reasoning [Leibniz]
     Full Idea: Although people can be made worse off by all other gifts, correct reasoning alone can only be for the good.
     From: Gottfried Leibniz (Preface to Universal Characteristic [1679])
     A reaction: How about a kind heart? Not everyone would agree with the remark, but philosophers should.
6. Mathematics / C. Sources of Mathematics / 4. Mathematical Empiricism / c. Against mathematical empiricism
It is possible that an omnipotent God might make one and two fail to equal three [Descartes]
     Full Idea: Since every basic truth depends on God's omnipotence, I would not dare to say that God cannot make it....that one and two should not be three.
     From: René Descartes (Letters to Antoine Arnauld [1645]), quoted by A.W. Moore - The Evolution of Modern Metaphysics 01.3
     A reaction: An unusual view. Most people would say that if Descartes can doubt something that simple, he should also doubt his reasons for believing in God's existence.
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / b. Rational ethics
Maybe final value rests on the extrinsic property of being valued by a rational agent [Korsgaard, by Orsi]
     Full Idea: Korsgaard argues for the ultimate dependence of final value on the extrinsic property of being valued by a rational agent.
     From: report of Christine M. Korsgaard (Creating the Kingdom of Ends [1992]) by Francesco Orsi - Value Theory 2.3 n4
     A reaction: This hyper-Kantian view doesn't strike me as very plausible. Not philosophical theory which entirely cuts animals out of the story has much appeal for me.
