None of the above. It's E: it's rational to act only in one's own interest, and it's irrational to act only in the interest of others. Since rational is not exactly equivalent to what you ought to do, this is distinct from B (but it could imply B).

  • but "rational egoism" is a thesis about what we ought to do, right? – user25714 Jul 25 '17 at 11:22
  • We ought to do something either because it is rational or because it is moral, but something can be rational without being moral. So one could subscribe to B: you ought to be selfish for moral reasons, without subscribing to D. – Quentin Ruyant Jul 25 '17 at 13:22
  • It's just that "ought" is more general than "rational" – Quentin Ruyant Jul 25 '17 at 13:26
  • yes, but "rational egoism" is a thesis about what we ought to do, it's not the same as any combination of the terns "rational" and "egoism" – user25714 Jul 26 '17 at 10:30
