With this argument, why even bother with the façade of classes and grades? Why not just have college be a four year cruise? It would be just as isolating, just as incubating, probably more fun. Students would get to see the world as they cruised around the globe. Those who wanted to learn, write, or discourse could absolutely do it, and those that just want to party wouldn't have to have grades or 9am classes to bother them. I've have been thinking of this for a while now. This idea reminds me of the grade schools that have stopped having classes and tests; the kids just study or do what they want, and come out just as prepared (according to the tests) as those from a public school.
