Kant's Synthetic a Priori and Live Needs

I assumed you to enjoy it because he does play off a Kant against live needs and back. Yes. There's some good dialogue. I read a lot of the, I read a good 25 or so maybe 30 pages. He says philosophy is not dialogue, but it's bringing out what live needs could have said back. And yet his system stands or falls with allowing this synthetic a priori judgment. It's focused solely on problems, which I think is the exception.
