I think the reliance on possible worlds is something that keeps coming up in moral thinking. I haven't investigated this as yet, but I think David Lewis might be on to something with his modal realism - there has to be something that gives these appeals to possible worlds the strength they feel like they have.
Thank you for these lectures. Romans 10:4 For Christ is the end of the law for righteousness to every one that believeth. John 16:13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come. Romans 8:4 That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
Concerning Kant's respect for law and Hume's desire and passion conflict: Rom 7:14 For we know that the law is spiritual: but I am carnal, sold under sin. Rom 7:15 For that which I do I allow not: for what I would, that do I not; but what I hate, that do I. Rom 7:16 If then I do that which I would not, I consent unto the law that it is good. Rom 7:17 Now then it is no more I that do it, but sin that dwelleth in me. Rom 7:18 For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not. Rom 7:19 For the good that I would I do not: but the evil which I would not, that I do. Rom 7:20 Now if I do that I would not, it is no more I that do it, but sin that dwelleth in me. Rom 7:21 I find then a law, that, when I would do good, evil is present with me. Rom 7:22 For I delight in the law of God after the inward man: Rom 7:23 But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members. Psalms 119:99 I have more understanding than all my teachers: for thy testimonies are my meditation. Psalms 119:100 I understand more than the ancients, because I keep thy precepts. Psalms 119:101 I have refrained my feet from every evil way, that I might keep thy word.
