What did Keynes argue about aggregate demand?

What did Keynes argue is not stable and can change unexpectedly?
Keynes argued that, for reasons we explain shortly, aggregate demand is not stable—that it can change unexpectedly. Suppose the economy starts where AD intersects SRAS at P0 and Yp. Because Yp is potential output, the economy is at full employment. Because AD is volatile, it can easily fall.

What did Keynes say about the level of aggregate demand?
