Q. Can you give an example of different human activities? A. Take two simple examples in order to understand the idea. To build a house, effort is needed at every moment, every single brick must be put into place with a certain effort; no triad passes into another triad without effort. At last the house is built and furnished. Then, if you want to burn it, you just strike a match and put it to something inflammable, and the house is burnt. If you go deeper into it you will see that these are two different activities. You cannot build a house by the same activity as you burn it. In the second case one triad passes into another without any effort, automatically, after the first initial effort of striking a match. Examples of the third kind of triad, in our experience, can be found only in conscious work, not identified work, or in some activity that has a peculiar quality of its own that cannot be imitated by others, such as artistic creation. Efforts at self remembering and not identifying belong to this category. If you think about it you will understand that in order to paint a good picture, for instance, one must use a different triad from the one used in building a house or the one used for burning a house; something else is needed. Another triad may be called invention, discovery, craft. If you think about these four different activities, they will give you material for observing and comparing. Try to see why and in what they are different.
