PHILOS 8 Chapter Notes - Chapter 1: Logical Positivism
Document Summary
Synthetic claims are knowable a posteriori: all real knowledge (i. e. knowledge of synthetic truths) has a posteriori. There are two apples true, because of the definitions of the two apples being there and the state of the world (which consists of having two apples on the table and by how many there are). Verifiability theory of meaning: the meaning of a sentence consists in its method of verification. it is truth or false. To know the meaning of a sentence, is to know the method of how to test whether. Find every patch of snow that has existed and see whether it is white or not. If all sentences are meaningless, there"s no way of testing that sentence, to test sentence you must know it"s meaning. Verifiability/testability: a sentence is testable/verifiable means that a sentence is capable of being shown to be true or false by means of observation. Scientific hypotheses have meaning because they are verifiable/testable.
