The philosophy of time travel is a sub-field of metaphysics – the study of what there is and what things are like – that considers questions about the possibility of time travel and what a world in which time travel is possible looks like. These questions range from whether time travel is actually possible, to how time travellers can act in the past or future. This thesis delves into a particularly interesting, yet historically undertreated theme: the abilities of time travellers (...) and relatedly their freedom as well. The abilities and freedom of time travellers has been the source of a lot of recent discussion with some polarising views. The minority (which includes Lewis (1976), but also Ted Sider (2002)) argue for the affirmative – that time travellers are free and have the same (or perhaps more) abilities as non-time travellers. The majority (which includes Kadri Vihvelin (1996), Michael Rea (2005), Stephanie Rennick (2015), Alison Fernandes (2020), amongst others) argue for the negative, that time travellers do not have exactly the same freedoms and abilities as non-time travellers. I think that it is a mistake to be so pessimistic about the abilities and freedom of time travellers. I treat concerns about the freedom of time travellers and concerns about the abilities of time travellers as two sides of the same coin. Therefore, in what follows, I argue for two related conclusions. First, I argue that time travellers have all sorts of abilities. Second, I argue that time travellers are just as free as non-time travellers. In arguing for these conclusions, I first produce a novel analysis of ability which reveals important details about how abilities track inputs rather than outputs. Second, I use this new analysis of ability to present a new compatibilist account of free will. If I am right in arguing positively for the abilities and freedoms of time travellers, then this has large implications for both the current time travel discourse and the general debate surrounding freedom. Significantly, I am arguing against some prominent views about time travel and in suggesting that these views are mistaken, I am presenting new ideas about ability and freedom: specifically, that time travellers have the ability and are free to do impossible things.

The "conservative" holds that mental disorder exculpates only if it is evidence of a standard excuse or justification, i.e., one that a mentally "normal" person could have. The Liberal holds that mental disorder sometimes exculpates in itself. I argue that moral culpability in the case of mental disorder is often moot, and that the real issue is what a court should be allowed to do with such individuals. This undermines the idea that culpability is a necessary condition for sentencing, but (...) we already have that in cases of strict liability, and there seems to be no viable alternative in any case.

My three main points are: Mental disease is a metaphor, but mental illness is not. Feeling ill and having a physical illness are logically related. If there were no such thing as feeling ill, there would be no such thing as suffering from a physical illness. Yet there is no logical connection between feeling ill and being mentally ill. Mental illness is manifested in various forms of behaviour, for example, suspiciousness, elation, depression, etc.; if a form of behaviour is to (...) count as mental illness, it has to be an insane form; yet it is possible to be mentally ill without being insane and it is possible to be insane without being mentally ill.

From 1965, the Swedish penal law does not require accountability as a condition for criminal responsibility. Instead, severely mentally disordered offenders are sentenced to forensic psychiatric care. The process that led to the present legislation had its origins in a critique of the concept of accountability that was first launched 50 years earlier by the founding father of Swedish forensic psychiatry, Olof Kinberg. The concept severe mental disorder is part of the Criminal Code as well as the Compulsory Mental Act. (...) The medical conditions for being sentenced to forensic psychiatric care are supposed to be the same as those for being admitted to involuntary psychiatric care. What these conditions are is not regulated in any law. For the guidance of the courts and others, there is a collection of examples in the government bill drafting the legislation in question. On the basis of these examples the content of the concept of severe mental disorder is chiselled out. However, the purposes of imposing penal law sanction and admitting someone to psychiatric care are not the same, and therefore the content of the concept severe mental disorder is bound to differ accordingly. Severe mental disorder is a legal concept that masks as a psychiatric one. In its applications in penal law, the court determines its content. But for the forensic psychiatrist it is more natural to interpret the term as a medical one. This creates a tension that has led to several controversies in recent criminal cases in Sweden. The best way to alleviate the situation is to discard the concept of severe mental disorder from criminal law. This will allow for a better separation of the roles of the psychiatrist and the court.

In this article, I argue that as we learn more about how we might intervene in the brain in ways that impact human behavior, the scope of what counts as “moral behavior” becomes smaller and smaller because things we successfully manipulate using evidence-based science are often things that fall outside the sphere of morality. Consequently, the argument that we are morally obligated to morally enhance our neighbors starts to fall apart, not because humans should be free to make terrible choices, (...) but because morality is not something subject to such manipulation. To illustrate my argument, I shall use the rise of veteran diversion courts in the United States as a putative instance of an intervention designed to change human behavior for the better. Part of my purpose in working my way through this case study is to demonstrate that many philosophers have the psychology of immoral action wrong. (shrink)

The purpose of this work is to offer a critical examination of Immanuel Kant's ethic of suicide. Kant's suicidology marks an influential view regarding the moral stature of suicide, yet one that remains incomplete in important respects. Because Kant's moral views are rationalistic, they restrict moral consideration to rational entities. Many people who commit suicide are not rational at the time of its commission, for they suffer from severe mental illness. Because of this, Kant's suicidology devastatingly excludes certain human demographics (...) from moral consideration, current Canadian statistics indicating that such people mark one of the highest populations at risk of committing suicide in the first place. This work contains a presentation, analysis, and critique of Kant's ethic of suicide, leading to an attempt to state criteria for an adequate suicidology.Dept. of Philosophy.

The author presents a model of moral responsibility based on the actual sequence and the notion of reason-responsiveness, and draws an analogy between this model and Robert Nozick’s model of knowledge based on the actual sequence. In addition, the concept of semicompatibilism is introduced and explained.
