I have been reading a new book of Freud’s and other things by his disciples. They are settling down to a steadier pace, and reducing their paradoxes to very much what everybody has always known.

Einstein I do not attempt to read: I am willing to have a maximum of “relativity”; but I wonder if they have ever considered that if “relative” systems have no connexion and no common object, each is absolute; and if they have a common object, or form a connected group of perspectives, then they are only relative views, like optical illusions, and the universe is not ambiguous in its true form.
