Paternalism occurs when someone acts to make a decision for another or acts to prevent another from carrying out a decision on the premise that such an action is for that person's own good. In healthcare, paternalistic measures are often used when dealing with those who are mentally unstable, who have a disease such as Alzheimer's, or are otherwise incapacitated from making fully rational choices for themselves. When acting paternalistically toward someone, there is always tension between the need to respect that person's autonomy and the moral obligation to help others. However, how much autonomy do those we treat paternalistically really have? John and Ken introduce the topic of paternalism by discussing the way in which we treat children. Ken asks the question: do we treat children paternalistically because they are not rational? John argues that we do and in fact should act paternalistically toward children, making decisions for them in accordance with what we think is best—with how we think their future adult selves will approve. We can divide children into two groups: elementary school children and teenagers. True children or very young people have no ability to acquire the information, reasoning skills, and evaluative capacities to make autonomous decisions. Teenagers, on the other hand, have the rational capacity to make decisions and have desires that they are capable of arguing for vigorously. Still, adults can be justified in acting paternalistically toward teenagers who are in the process of figuring out how best to use their newly- acquired autonomy. Ken makes the point that, just as we decide what's best for children based on the perceived wishes of their future selves, it might be the case that we should decide what's best for a patient with Alzheimer's based on the wishes of her past selves. However John counters that, although this conception would produce symmetry in our thinking about the issue, there is a difference between the past and the future. For an Alzheimer's patient who has lost her memory and with it her reasoning capacity, there is no future self who will understand or make connections with who they were in the past. In such circumstances, why shouldn't the present desires of the person be respected?

Guest Agnieszka Jaworska claims there needs to be a balanced framework for evaluating and making decisions that reflect both the interests and values of the fully autonomous person and the interests and values of the patient with Alzheimer's. Alzheimer's is a disease that moves in stages, gradually diminishing a person's autonomy. Our ability to have convictions and a moral sense is what it means to have autonomy. So, consider a person who still has some elements of autonomy but doesn't have full autonomy because of Alzheimer's disease. The fact that they have some autonomy doesn't mean we shouldn't make decisions for them: it means that we shouldn't make decisions for them that are based exclusively on their prior values and convictions. We should respect their wishes to the extent that they are still autonomous and make decisions that reflect the patients' current values as well.

In further discussion about autonomy, John quotes John Stuart Mill from his book On Liberty. Mill claims that no one should be allowed to overpower a person's will regardless of whether or not others feel doing so would be for the person's own good, be a wise choice, or be morally right. The only exception to this rule is when the action a person wishes to undertake will harm others. John is concerned both with whether we can accept this claim and what it' implications are for Alzheimer's patients who are in the most early stages of the disease. Jaworska mainly addresses his second concern. For ordinary adults, the current understanding is that it is wrong to interfere with a person's will. However, in the case of Alzheimer's patients, it is unclear whether they have fully-formed rational capacities or not. According to Jaworska, a will has several components. The first is the ability to conceptualize the good—i.e. a sense of right and wrong when choosing to act on desires. Then, there is the ability to criticize or critique this conception, the ability to make a decision based on these considerations, and the ability to follow through with a decision. A person can have part of this capacity or will while lacking other necessary components. For example, a person could have the ability to form convictions while lacking the ability to critically evaluate and practically carry out her decisions. People with early-stage Alzheimer's, Jaworska contends, experience these types of limits in their decision-making capacity which is why they are not fully autonomous and, consequently, do not fall in the general category of individuals to which Mill's statement is meant to apply.

Just a little while before that, Eddie and Doris were driving from New Hampshire to California when, for the first time ever, Eddie let Doris drive. Doris explains how, at first, the signs of Alzheimer's arose almost imperceptibly in particular changes that she noticed but that were so small that no one else could tell the difference. Then, as the years went by after his diagnosis, Eddie's condition grew significantly worse.
