Short idea (69): Sensations are like the sounds of the individual instruments in an orchestra; Feelings are like the sound of the whole orchestra. A Sensation is like a moving picture of an individual leaf on a tree moving in the wind; A Feeling is like a moving picture of all the leaves (and the whole tree) moving in the wind.

Short idea (84): If we make an analogy between the Imagination, Sensation, Need, and Thinking on the one hand and four rivers on the other, then there is a place where the rivers merge with each other and eventually form an ocean. Or, we can start with the idea of an ocean and picture the Imagination, Sensation, Need, and Thinking as four rivers that separate and flow out of it. — Without the ocean and its rivers we would all be dead. On the other hand, people often get swept away and drown in one of them. It's naive to forget the dangers of the rivers and the ocean and equally naive (and even fanatically suicidal) to try to get rid of them.

Short idea (113): From a developmental point of view, I think that Sensation must have been the first adaptive psychological function to appear (every living cell senses — as do human infants). Imagination assumes Sensation and builds on it, and I think it must have been the second function to appear (dogs dream). Thinking assumes Imagination and Sensation and integrates them into itself, and, I think, it must have been the third of the functions to appear (language is needed for thinking; infants don't yet have language). Reflection, Evaluating, Moral and Ethical Reflection, and Planning integrate Sensation, Imagination, and Thinking, and I think it is the fourth function to arise and probably does not arise in everyone. Wisdom couldn't develop without being able to build on the previous four functions and there would also have to be character traits present such as courage. And, if there is any psychological function further along than Wisdom, perhaps some Unifying function, it would develop, if at all, only after everything else was in place and functioning.

Short idea (131): To a vast degree, the world is not what we think or imagine or perceive or expect or want it to be.

Short idea (135): It is correct to say that, at any moment, we have five senses (some say six or seven) that are functioning to get information about the environment in which we live. It is equally true that, at any moment, we have one overall sensibility or sensorium which we can, if we want, analyze into sights and sounds and tastes and feelings which we can label as inside us or outside.
