Lecture IV

But if one judges these matters out of real life experience and not intellectually, the situation is not unlike one where a number of people have come together to discuss and decide what the performance of an efficient stove should be. Obviously they would come up with a whole list of “categorical imperatives,” such as that the stove must be capable of heating the room adequately, it must not emit smoke, and so on. But, though the various points made may be convincing enough, knowledge of them alone would hardly result in the necessary know-how to light it, keep it going, and control its heat. To be able to do this one has to learn other things as well. In any case, depending on the location of the room, the condition of the chimney and possibly on other factors as well, it may not even be possible to fulfill the conditions so competently set forth.
