tight-rope

Your brother is a sensitive person. Aesthetically, ethically, and intellectually he is in fact hypersensitive. As a result, it would seem that he was born only to torture himself. He has none of that saving dullness of intelligence which sees little difference between A and B. To him it must be either A or B. And if it is to be A, its shape, degree, and shade of color must precisely match his own conception of it; otherwise he will not accept it. Your brother, being sensitive, is all his life walking on a line he has chosen__ line as precarious as a tight rope. At the same time he impatiently demands that others also tread an equally precarious rope, without missing their footing. It would be a mistake, though, to think that this stems from selfishness. Imagine a world which could react exactly the way your brother expects; that world would undoubtedly be far more advanced than the world as it is now. Consequently, he detests the world which is__esthetically, intellectually, and ethically__ot as advanced as he is himself. That's why it's different from mere selfishness, I think.
