 Paul Schofield (2015) defends something closer to an unwaivable juridical duty to oneself. Schofield argues that you owe it to yourself not to cause yourself harm in the future – as you might by smoking heavily in your youth and giving yourself lung cancer. You also owe it to yourself not to hamstring your future choices, as in Derek Parfit’s (1984, 327–28) example of the Russian nobleman, who arranges as a young socialist to prevent his future self from funding conservative causes. Schofield’s picture is this. You owe a certain action to someone when they can legitimately demand that you do it. But you can also imagine demands made by yourself of yourself, from different perspectives within your life. When you smoke, causing yourself to suffer in the future, you can look upon this either from the perspective of the future sufferer or the present smoker. The future smoker – that is, you from your future perspective – could justifiably demand less smoking from you in the present, generating a duty not to smoke. Moreover, you cannot presently waive this duty, since you do not now occupy the right perspective (Schofield 2015, 17; see also Schofield 2019).
