Wow, I hadn't realized Rabbi Dr. Norman Lamm was such an existentialist.
It's very interesting to me how his paper follows so many of the themes that I've been thinking through this past long while. That it is better to open one's mind to speculative truth even while the danger of falsehood may enter, for it may be worse to close one's mind to everything, thus locking truth out. And that faith-acts, like Halacha, demonstrate a key trust, a 'faith-in', even while substantive cognitive doubts may exist as merely theoretical problems.
Ironically, while all of these ideas help me to understand the most crucial of religious ideas - i.e. metaphysics and the object of faith in itself, they don't help at all when we bring simple historical propositions into the picture. Exodus, revelation, the validity of our mesorah. He glosses over these kinds of concepts at the beginning of his paper but these are not the abstract philosophical issues that can be dealt with by existentialist philosophies. For the Orthodox system they are true out of dogmatic necessity, but how can the skeptical intellectual (I flatter myself) take that as reason enough to believe?
I don't wonder how Rabbi Lamm dealt with those issues, but I wonder how Dr. Lamm does.
