13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / b. Gettier problem
Being a true justified belief is not a sufficient condition for knowledge [Gettier]
     Full Idea: The claim that someone knows a proposition if it is true, it is believed, and the person is justified in their belief is false, in that the conditions do not state a sufficient condition for the claim.
     From: Edmund L. Gettier (Is Justified True Belief Knowledge? [1963], p.145)
     A reaction: This is the beginning of the famous Gettier Problem, which has motivated most epistemology for the last forty years. Gettier implies that justification is necessary, even if it is not sufficient. He gives two counterexamples.
18. Thought / B. Mechanics of Thought / 1. Psychology
In no important way can psychology be reduced to the physical sciences [Davidson]
     Full Idea: There is no important sense in which psychology can be reduced to the physical sciences.
     From: Donald Davidson (The Material Mind [1973], p.259)
     A reaction: In no 'important' way can the beauty of the Lake District be reduced to geology - but it is geology. 'Important' to whom? To a metaphysician, I would say psychology does reduce to physics, and that is important, but it is not important to a psychologist.
23. Ethics / B. Contract Ethics / 3. Promise Keeping
If lies were ever acceptable, with would undermine all duties based on contract [Kant]
     Full Idea: Truthfulness is a duty that must be regarded as the basis of all duties to be grounded on a contract, the law of which is made uncertain and useless if even the least exception to it is admitted.
     From: Immanuel Kant (On a supposed right to lie [1797], p.30)
     A reaction: Should we keep contracts which are made by means of deception and coercion? Where could such absolute authority for contracts come from? Do contracts and treaties tend to lapse after a long period of time?
23. Ethics / D. Deontological Ethics / 2. Duty
The law will protect you if you tell a truth which results in murder [Kant]
     Full Idea: If you have by a lie prevented someone bent on murder from committing the deed, then you are legally accountable for all the consequences that might arise from it. But if you keep strictly to the truth, then public justice can hold nothing against you.
     From: Immanuel Kant (On a supposed right to lie [1797], p.29)
     A reaction: Shocking, from a supposedly great thinker. Cowardly hiding behind a perverse law. What would Kant do if the law were changed, to condemn someone who told a truth which would probably lead to a murder? Would he accept a jail sentence?
