I got some good responses to my The Logic of Rationalism post, in paticular I wanted to make a full response to this post:

Which brings me to this post. With respect to the author, aren’t you just advocating subjectivism? And are you really willing to say with intellectual honesty that even if rationalism is supported only by circular logic that you’d still use it because you don’t like the alternative? Because, and I am an expert in this arena, that would be faith, bro.

The problem here lies with Hume’s Problem of Induction: simply stated that there is no rational or non-circular argument for using induction.  Now atheist and fundamentalist theist both use induction everyday (if you open your fridge and don’t expect a monster to jump out and kill you – you’re using induction).  So every one of us makes a “faith leap” (if you want to call it that) in assuming induction holds (since it seems to – but that statement is itself inductive reasoning).  So I guess what I was intending to say is that without induction our lives cannot be lived, we are evolved to live on the assumption and that’s all we can deal with.

Now as for subjectivism, I’d have to say that I’m more agnostic on this point.  As it stands I don’t think the universe has shown necessary objective/teleological evidence, but that’s not really to say there isn’t.  I need to think more on this before I’m really sure where I stand.

I should mention that using a methodology to refute a methodology is actually a rather common test. I mean, what’s the point of relying on a philosophy that can be used to discredit it itself?

At the risk of overkill, how do you know your rationalism is reliable? If you’re following the logical dictums of Descartes’ cogito ergo sum, how do you know that your thoughts are reliable? After all, atheists usually allege that reason itself evolved by chance [or some inexplicable yet benevolent mechanism called natural selection for which they also cannot posit a reasonable materialistic origins for] so how do we know your reason and hence your rationalism is reliable?

We don’t!  But for me, it seems that without the jump to induction and working from there we can’t function as “rational” beings (whatever that even means).  I think the point here is that these are deep philosophical and interesting questions, that very much get beyond the classical arguments in the “is there a god” debate.  I think an argument for god developed around these ideas would be one of the strongest I’ve seen/heard so far.

And, above all, what is the objective standard for your rationalism? Or is it subjectivism all along? “I believe therefore it must be. I hope.”

I hope this isn’t the case. I hope you can provide me with the objective standard of your rationalism. Otherwise, I fear, you will perhaps have disproven your own existence. If “I think, therefore I am,” what are the consequences if one is not thinking?

I don’t know about disproving my own existence, but I don’t know if Descarte was on the button with that one.  I’ll admit that I’m not a philosopher, but dabble a little with my spare courses.  I hope I responded somewhat to your questions (which are of the utmost interest), and I look forward to future thought and discussion on these topics (I’ll likely be writing/YouTubeing) more on this in the future.
