  1. PHL 201 Problems of Philosophy March 25th Chapter Five, ‘God’

  2. Overview • Faith that God exists vs. Justified Belief that God exists • The concept of God • The Ontological Argument • The First-Cause Argument • The Argument from Design • The Evidence of Miracles • The Utility of Belief in God • The Problem of Evil

  3. Faith that God exists vs. Justified Belief that God exists • Should religious claims (e.g. “There is a God”) be assessed in terms of truth and falsehood? • Can we find some reason to believe that God exists? • Fideism: The view that religious belief is based on faith, not on reason

  4. The Concept of God • Different cultures and religions offer quite different conceptions of God or Gods • The conception that interests Blackburn is shared by Judaism, Christianity, and Islam • God’s principal attributes (perfections) are: -Omnipotence (all-powerful) -Omniscience (all-knowing) - Goodness (all-good)

  5. The Ontological Argument • In his Meditations, Descartes offers several arguments for the existence of God • TheTrademarkArgument • A version of The Ontological Argument: • All perfections are properties of the Supreme Being. • Existence is a perfection. Therefore, • The Supreme Being has existence – i.e. God exists.

  6. The Ontological Argument • A version of Descartes’ argument was offered by an earlier philosopher/theologian, St. Anselm (1033-1109). The argument has 2 parts. Part 1: • The concept of God (the being with ALL perfections) is understood. • Whatever is understood exists in our minds. Therefore, • God exists in our minds.

  7. Part 2: • Suppose God exists only in our minds, and not in reality. • Then we can conceive of a being greater than God – one that really exists. • But “God” is defined as “that being than which nothing greater can be conceived”. • So, no greater being can be conceived. • But this contradicts our supposition (4) that God exists only in our minds. Therefore, • Our supposition that God exists only in our minds is false – i.e. God exists outside of our minds.

  8. Is this a sound argument? Some things to wonder about: • Is “existence” really a predicate? • Is existence a perfection? • Does the argument allow us to prove too much? - The Proof that Dreamboat exists (Think, p.156) • Does it make sense to compare things that exist in reality with things that exist in the mind? (Think, pp. 157-158)

  9. The First-Cause Argument • There are now things changing and causing change. • Something causes change only if it is caused to change by something else. • If something causes change only if it is caused to change by something else, then its causal chain is infinitely long. • But no causal chain is infinitely long. Therefore, • There is something that causes change, but is not caused to change by something else – i.e. there is a first-cause and it is God.

  10. Is this a sound argument? Some things to wonder about: • Why can’t there be an infinitely long series of causes and effects? • Why think that the first-cause, if there was one, must still exist? • Why think that the first-cause, if there was one, is God? • If God requires no cause in order to change or cause change, then why not just stop with the physical world?

  11. The Argument from Design Based on an analogy: The universe, as an ordered structure, resembles (or is analogous to) a mechanism (e.g. a watch) • The universe is like a mechanism. • Like effects have like causes. • The cause of a mechanism is an intelligent being. Therefore, probably • The cause of the universe is an intelligent being. • This cause is God (“The Wise Architect”)

  12. Is this a cogent argument? Some things to wonder about: • Is the analogy a good one? • Why think that the designer, if there was one, must still exist? • Why think that the designer, if there was one, is God? • Are there other hypotheses that would explain the existence of order in the universe?

  13. The Evidence of Miracles • Some people report having witnessed or experienced miracles. • Miracles, if they exist, are violations of natural regularities and natural laws. • If miracles occur, then probably there is a God. Therefore, • There is some evidence (i.e. the testimony of those who report miracles) that probably there is a God.

  14. Is this a cogent argument? David Hume’s Objection: • Suppose Jones offers a report, R, that a miracle occurred. • R is, of course, very improbable (because miracles are very improbable). Considering the following 2 possibilities, we should reject the one that is least probable: (a) Jones reports R, but R did not actually happen. (b) Jones reports R, and R actually occurred. But, clearly, the least likely of these options is the (b). So we should believe (a). (see Think, pp. 179-180)
