Alas, the 2014 edition of 6.803/6.833, The Human Intelligence Enterprise, is oversubscribed. Because of the discussion-oriented nature of the subject, there will, I regret, have to be a lottery following the first day of class, so you should have a back up plan in case the dice roll the wrong way.
To determine whether you want to enter the lottery, I recommend that you attend my "How to Speak" talk tomorrow, 11:00-12:00, 10-250, because about 1/3 of class time will be devoted to discussion of how to package ideas, and "How to Speak" is a good sample. Then, you should read the propspectus at http://courses.csail.mit.edu/6.803/prospectus.
Finally, if your interest holds, you should attend the first class on Wednesday.
Note that on the first day only the class will not meet in the scheduled room. Actual rooms will be announced here as soon as known On the first day, it doesn't matter which session you attend. I recommend the earlier section because it is a larger room and you will be sure to be able to sit down.
