• What is the foresight argument?

  It has the form of an attempt to see things the way that we will see them at some later point in time.

• What is the criterion of decision-stability?

  Our conviction that the decision was right should not be perturbed by information that reaches us after the decision

• What is hypothetical retrospection?

  alternative future developments are identified and comparatively assessed.

• Why is predicted regret not a suitable decision criterion?

  1. Regret is compatible with the conviction that what one did was morally right (you could regret something even if what you did was morally right)
  2. There are situations in which a person may feel regret whichever course she takes.

• 4.2 Specifying the branches

• What does specifying the branches mean?

  If hypothetical retrospection is performed to guide a decision, retrospections should be enacted in each of the branches at some point in time when the decision has been made or, subdivisions of future developments should be so constructed that we avoid, as far as possible, comparisons between branches that differ widely in their degrees of uncertainty in issues that are crucial for the decision

• Why must hypothetical retrospection be based on our actual values?

  1. We all have a tendency to acquiesce and to content ourselves with what the future brings us.
  2. It has to be based on the values we have when we deliberate, not on the values we believe that we will have at the future point in time at which the deliberation is hypothetically enacted

• What did Henry Sidwick mention about our values?

  a situation in which there is more than one alternative to choose between, but non of them is considered to be morally acceptable.

• What differs hypothetical retrospection from the maximin rule?
