Are You My Esrog?

A few minutes ago a colleague stopped me and another rabbi and shared an opinion of The Aruch HaShulchan. The approach is that we don't say a blessing thanking G-d for commanding us to do an action regarding mitzvot that are person to person because these are intuitive. This teacher's question was that this seemed "to fly in the face" with an idea that he has accepted as lore in the name of Rabbi Soloveichik. That approach is that even though certain mitzvot make sense to us we do them not because of our own logic, but because G-d said so.

The two of us that were asked the question had our interest piqued and had a lot to say about it. The colleague who asked the question needed to copy sheets, finish his lesson and run to class. Speaking of running to class, it's time for my next one. If you're interested in responses to my friend's question, let me know.
