[using reason to convince of God's existence]

11 ideas
For Aristotle God is defined in an axiom, for which there is no proof [Aristotle, by Frede,M]
     Full Idea: Aristotle is committed to the view that strictly speaking there is no proof of the essence and existence of God. There will be a real definition of him as an axiom of special theology, and then a deduction of theological theorems.
     From: report of Aristotle (Metaphysics [c.324 BCE], God) by Michael Frede - Aristotle's Conception of Metaphysics p.94
     A reaction: The cynical response would be 'why not start with a Great White Rabbit, then?', but I presume one must read what Aristotle says (late in 'Metaphysics') to understand why this particular axiom is chosen. Economy, power etc.?
God is defended by agreement, order, absurdity of denying God, and refutations [Sext.Empiricus]
     Full Idea: Arguments for God have four modes: from universal agreement, from the orderly arrangement of the universe, from the absurd consequences of denying God, and from undermining the opposing arguments.
     From: Sextus Empiricus (Against the Physicists (two books) [c.180], I.060)
     A reaction: [compressed] The loss of status of the argument from universal agreement has had a huge influence. We now realise that a very wide consensus is no guarantee of truth in anything.
God has given us no innate idea of himself [Locke]
     Full Idea: God has given us no innate idea of himself.
     From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.10.01)
     A reaction: This is rejection of Descartes' 'Trademark Argument' (Idea 2274). It is consistent with Locke's general assault on all innate ideas, as you might expect from an empiricist.
Without the principle of sufficient reason, God's existence could not be demonstrated [Leibniz]
     Full Idea: There is a fundamental axiom that 'nothing happens without reason', without which the existence of God and other great truths cannot be properly demonstrated.
     From: Gottfried Leibniz (New Essays on Human Understanding [1704], 2.21.13)
     A reaction: I'm rather drawn to the Principle of Sufficient Reason, but also to John Keats's 'negative capability'. Belief that there must be a reason in each case is not a justification for inventing a reason every time. There may be a reason for the universe....
There must be a God, because all sensible things must be perceived by him [Berkeley]
     Full Idea: I immediately and necessarily conclude the being of a God, because all sensible things must be perceived by him.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], II p.198)
     A reaction: Daft. This contradicts Berkeley's whole empiricist position, that existence depends on known experience. Who knows whether God is thinking about trees?
There must be a God, because I and my ideas are not independent [Berkeley]
     Full Idea: From the dependency I find in myself and my ideas, I do by an act of reason necessarily infer the existence of a God.
     From: George Berkeley (Three Dialogues of Hylas and Philonous [1713], III p.222)
     A reaction: No. Hume answered this, by showing how big abstract ideas are built up from experience. This is a future bishop's wish-fulfilment.
The objects of theological reasoning are too big for our minds [Hume]
     Full Idea: But in theological reasonings … we are employed upon objects, which, we must be sensible, are too large for our grasp.
     From: David Hume (Dialogues Concerning Natural Religion [1751], Part 1)
Only three proofs of God: the physico-theological (evidence), the cosmological (existence), the ontological (a priori) [Kant]
     Full Idea: There are three proofs of the existence of God: the physico-theological, the cosmological, and the ontological. There are no more of them, and there also cannot be any more.
     From: Immanuel Kant (Critique of Pure Reason [1781], B619/A591)
     A reaction: It is hard to deny this, though the 'physico-theological' group may be a sizeable family. The immediate difficulty may be that physical evidence supports something less than God, the cosmological is just speculation, and a priori proofs won't work.
The God of revealed religion can only be understood through pure speculative knowledge [Hegel]
     Full Idea: God is attainable in pure speculative knowledge alone and is only in that knowledge, and is only that knowledge itself, for He is Spirit; and this speculative knowledge is the knowledge of revealed religion.
     From: Georg W.F.Hegel (Phenomenology of Spirit [1807], p.461), quoted by Stephen Houlgate - An Introduction to Hegel 04 'Absolute'
     A reaction: If you were hoping to find out why Hegel believed in God, I fear this is the best evidence available. He is evidently opposed to natural theology. Hegel's language makes it very hard to grasp how we sees the nature of God.
If the God hypothesis works well, then it is true [James]
     Full Idea: On pragmatistic principles, if the hypothesis of God works satisfactorily in the widest sense of the word, it is true.
     From: William James (Pragmatism - eight lectures [1907], Lec 8)
     A reaction: The truth of God's existence certainly is a challenging test case for the pragmatic theory of truth, and James really bites the bullet here. Pragmatism may ultimately founder on the impossibility of specifying what 'works satisfactorily' means.
'Natural theology' aims to prove God to anyone (not just believers) by reason or argument [Davies,B]
     Full Idea: 'Natural theology' is the attempt to show that belief in God's existence can be defended with reference to reason or argument which ought to be acceptable to anyone, not simply to those who believe in God's existence.
     From: Brian Davies (Introduction to the Philosophy of Religion [1982], 1 'Other')
     A reaction: I assume by 'reason or argument' he primarily means evidence (plus the ontological argument). He cites Karl Barth as objecting to the assumption of natural theology (preferring revelation). Presumably Kierkegaard offers a rival view too.
