It's really important to think for yourself and reflect on the arguments you've heard in previous weeks: you might uncover places where you disagree, or mistakes in the reasoning. And even if you don't you'll probably understand the ideas more deeply if you've thought about their weakest points.

So this week, we encourage you to take some time to reflect on your confusion and concerns about the ideas so far and to read up on some of the strongest counterarguments.

Fellows will be our “guest speakers” for this week, as they participate in lightning talks.
