Schrödinger writes after seeing BR's signature on an invitation to the Kitzbuhel meeting, which he replied to Rabinowitch as saying that due to his unreliable health he cannot formally accept the invitation, but would if he could, and would therefore make his own reservations.

He replies to a letter which BR wrote 5 January which he did not answer initially, "... lest you get frightened at the prospect of a continued correspondence. But allow me to comment on one point in which I disagree with you. With regard to the general ethical demand you say: I do not think one should prefer one's neighbour's good to one's own. I think one should prefer the greater good, whoever is to enjoy it", which Schrödinger goes on to address with several examples of puzzles in ethics.
