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) |
19406 | I strongly believe in the actual infinite, which indicates the perfections of its author [Leibniz] |
Full Idea: I am so much for the actual infinite that instead of admitting that nature abhors it, as is commonly said, I hold that it affects nature everywhere in order to indicate the perfections of its author. | |
From: Gottfried Leibniz (Reply to Foucher [1693], p.99) | |
A reaction: I would have thought that, for Leibniz, while infinities indicate the perfections of their author, that is not the reason why they exist. God wasn't, presumably, showing off. Leibniz does not think we can actually know these infinities. |
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'). |
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) |
