1. Philosophy / C. History of Philosophy / 4. Later European Philosophy / b. Seventeenth century philosophy
Most philosophers start with reality and then examine knowledge; Descartes put the study of knowledge first
                        Full Idea: Some philosophers (e.g Plato) begin with an account of reality, and then appended an account of how we can know it, ..but Descartes turned the tables, insisting that we must first decide what we can know.
                        From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.2)
1. Philosophy / F. Analytic Philosophy / 2. Conceptual Analysis
You cannot demand an analysis of a concept without knowing the purpose of the analysis
                        Full Idea: An analysis is always relative to some objective. It makes no sense to simply demand an analysis of goodness, knowledge, beauty or truth, without some indication of the purpose of the analysis.
                        From: Keith Lehrer (Theory of Knowledge (2nd edn) [2000], I p.7)
                        A reaction: Your dismantling of a car will go better if you know what a car is for, but you can still take it apart in ignorance.
