7 ideas
21959 | Metaphysics is the most general attempt to make sense of things [Moore,AW] |
Full Idea: Metaphysics is the most general attempt to make sense of things. | |
From: A.W. Moore (The Evolution of Modern Metaphysics [2012], Intro) | |
A reaction: This is the first sentence of Moore's book, and a touchstone idea all the way through. It stands up well, because it says enough without committing to too much. I have to agree with it. It implies explanation as the key. I like generality too. |
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) |
13547 | Limitation of Size is weak (Fs only collect is something the same size does) or strong (fewer Fs than objects) [Boolos, by Potter] |
Full Idea: Weak Limitation of Size: If there are no more Fs than Gs and the Gs form a collection, then Fs form a collection. Strong Limitation of Size: A property F fails to be collectivising iff there are as many Fs as there are objects. | |
From: report of George Boolos (Iteration Again [1989]) by Michael Potter - Set Theory and Its Philosophy 13.5 |
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) |
21958 | Appearances are nothing beyond representations, which is transcendental ideality [Moore,AW] |
Full Idea: Appearances in general are nothing outside our representations, which is just what we mean by transcendental ideality. | |
From: A.W. Moore (The Evolution of Modern Metaphysics [2012], B535/A507) |
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) |
