3 ideas
| 21757 | Philosophy is the conceptual essence of the shape of history [Hegel] |
| Full Idea: Philosophy is the supreme blossom - the concept - of the entire shape of history, the consciousness and the spiritual essence of the whole situation, the spirit of the age as the spirit present and aware of itself in thought. | |
| From: Georg W.F.Hegel (Lectures on the History of Philosophy [1830], p.25), quoted by Stephen Houlgate - An Introduction to Hegel 01 | |
| A reaction: This sees philosophy as intrinsically historical, which is a founding idea for 'continental' philosophy. Analysis is tied to science, in which the history of the subject is seen as irrelevant to its truth. Does this mean we can't go back to Aristotle? |
| 13832 | Natural deduction shows the heart of reasoning (and sequent calculus is just a tool) [Gentzen, by Hacking] |
| Full Idea: Gentzen thought that his natural deduction gets at the heart of logical reasoning, and used the sequent calculus only as a convenient tool for proving his chief results. | |
| From: report of Gerhard Gentzen (Investigations into Logical Deduction [1935]) by Ian Hacking - What is Logic? §05 |
| 20695 | God's eternal power and deity are clearly seen in what has been created [Paul] |
| Full Idea: From the creation of the world God's invisible nature, namely his eternal power and deity, are clearly perceived in the things that have been made. | |
| From: St Paul (06: Romans [c.55], 19-21), quoted by Brian Davies - Introduction to the Philosophy of Religion | |
| A reaction: St Paul says that for this reason the Gentiles are 'without excuse' for not believing (which means they are in trouble if Christians ever gain political power). Davies says it is unusual to find an argument for God's existence in the Bible. |
