6 ideas
21962 | Metaphysics is the roots of the tree of science [Descartes] |
Full Idea: The whole of philosophy is like a tree. The roots are metaphysics, the trunk is physics, and the branches emerging from the trunk are all the other sciences. | |
From: René Descartes (Preface to 'Principles of Philosophy' [1647]), quoted by A.W. Moore - The Evolution of Modern Metaphysics 01.2 | |
A reaction: If Descartes had not believed this he would not have bothered with metaphysics, and philosophy might have been dead by 1650. |
3659 | I know the truth that God exists and is the author of truth [Descartes] |
Full Idea: I have very clearly deduced the following truths, that there is a God who is the author of all that is in the world, and who is the source of all truth. | |
From: René Descartes (Preface to 'Principles of Philosophy' [1647], p.180) |
3657 | Understanding, not the senses, gives certainty [Descartes] |
Full Idea: Certainty is not in the sense but in the understanding alone, when it has evident perceptions. | |
From: René Descartes (Preface to 'Principles of Philosophy' [1647], p.177) |
7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom. | |
From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88) | |
A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate'). |
8338 | A phenomenalist about objects has to be a regularity theorist about causation [Strawson,G] |
Full Idea: If you are a phenomenalist about objects, then there is an important sense in which you ought to be a Regularity theorist about what causation is, in such objects. | |
From: Galen Strawson (The Secret Connexion [1989], App C) | |
A reaction: Strawson is denying that Hume is a phenomenalist. One might go a little further, and say that a phenomenalist should abandon the idea of causation (as Russell did). |
3660 | Atheism arises from empiricism, because God is intangible [Descartes] |
Full Idea: The existence of God has been doubted by some, because they attributed too much to the perceptions of the senses, and God can be neither seen nor touched. | |
From: René Descartes (Preface to 'Principles of Philosophy' [1647], p.180) |
