A few selected quotes:
The basis of Orthodox Judaism is EXPERIENCE.
What do I mean? I mean the experience of keeping Halachah. The experience of keeping Shabbat. The experience of keeping Kashrut. The experience of learning Torah. The experience of God. We all do these things. We all feel it. We know it to be true on the basis of our experience. We see it works. We see the results. We see how a dedication to these ideals produces upstanding communities, families and individuals.
We know Torah is true because we experience it. And we know our fathers experienced it and we know their fathers experienced it too, all the way back to an event we call Sinai.It's almost to obvious to really commment on, go read the post. It is rather long, but it's a quick read.
And of course, experience is the foundation for Western Philosophy too. ‘I think therefore I am’. And how do we know we think? Because we experience it!
