The Seven Years War and the Great Awakening: Crash Course US History #5
In which John Green teaches you about the beginnings of the American Revolution in a video titled The Seven Years War. Confusing? Maybe. John argues that the Seven Years War, which is often called the French and Indian War in the US, laid a lot of the groundwork for the Revolution. More confusing? Why does this war have two names? Why were the French and Indians fighting each other? The Seven Years war was actually a global war that went on for nine years. (10:40)

3.4 Cognitive and non-cognitive states

At several points in the Reading, James draws a sharp contrast between emotions and what he terms ‘cognitions’. The distinction between cognitive and non-cognitive states will crop up fairly regularly from now on, so I shall pause at this point to make it clear how I am going to understand this distinction.
