Short idea (23): Mattress ads claim that the reason a person sleeps badly is because of the mattress, and, if you use their mattresses, you will sleep perfectly. It is the springs or the stuffing or whatever. This is a good example of an attempt to explain a psychological state of unrest or discomfort by reference to a thing or event in the external world.
Short idea (111) : There are four kinds of hurts. Hurts administered by an enemy, hurts administered by a friend, hurts administered by ourselves, and imaginary hurts. Each requires a different kind of response.
Short idea (119): We all feel filled with Energy sometimes, bursting with Energy; at other times listless and sluggish and filled with inertia. This feeling of Energy has a psychological label: Libido (sometimes "Libido" is used to refer to all psychological energy, sometimes only to sexual energy). If we look at objects in the physical world we can often see what fills them with energy. For example, a moving object hits one that is still, and the second objects moves, filled with the energy transferred from the first object. It is not so easy to see what fills us with the feeling of Energy or takes away the feeling. If we do see what does, it is difficult to understand how this can happen. For example, how can bad news make us feel all the Energy draining from us? We may be able to picture how a virus could take the wind out of our sails, but how can hearing bad news do it?
