Is There a Market of Ideas?

In the caricature of democracy that we have to day, instead of seeing democracy as a way to organize e deliberation, we see democracy just as a deciding ism. And i guess it's also a question of if you have plurality with or without accountability? Yes, of course. Because the only accountability then is the accountability of success. and you see how elections become that. It's not about which idea wins. It's about which idea allows an another idea to flourish.
