If f he is told that something is the way it is, he will think: Well, it could probably just as well be otherwise. So the sense of possibility could be defined outright as the ability to conceive of everything there might be just as well, and to attach no more importance to what is than to what is not. The consequences of so creative a disposition can be remarkable, and may, regretably, often make what people admire seem wrong, and what is taboo permissible, or, also, make both a matter of indifference. Such possibilists are said to inhabit a more delicate medium, a hazy medium of mist, fantasy, daydreams, and the subjunctive mood...
Putting it another and perhaps better way, the man with an ordinary sense of reality is like a fish that nibbles at the hook but is unaware of the line, while the man with that sense of reality which can also be called a sense of possibility trawls a line through the water and has no idea whetherthere's any bait on it. His extraordinary indifference to the life snapping at the abit is matched by the risk he runs of doing utterly eccentric things. An impractical man--which he not only seems to be, but really is--will always beunreliable and unpredictable in his dealings with others. He will engage in actions that mean something else to him than to others, but he is at peace with himself about everything as long as he can make it all come together in a fine idea. He is quite capable of regarding a crime that brings harm to another person merely as a lapse to be blamed not on the criminal but on the society that produced the criminal. But it remains doubtful whether he would accept a slap in the face with the same detatchment, or take it impersonally as one takes the bite of a dog. The chances are that he would first hit back and then on reflection decide that he shouldn't have. Morever, if someone were to take away his beloved, it is most unlikely that he would today be quite ready to discount the reality of his loss and find compensation in some surprising new reaction.
