Since the dawn of the internet, pornography has effectively become ubiquitous, pervasive, and increasingly normalised. Study findings show remarkable similarities in how the brain reacts to pornography, and other known addictive substances, and indicate that consuming pornography is comparable to consuming other known addictive substances. Moreover, two of the biggest risk factors for addiction are the substance’s availability and its easy accessibility, particularly in the case of younger persons. To date, pornography addiction has been conceptualised as a behavioural addiction. However, (...) the body of research data on pornography addiction does not provide conclusive support for behavioural addiction. The aim of this thesis is to put forward the idea that pornography can, and should, be conceptualised as an addictive substance, and, that when pornography is consumed, an addictive substance is consumed. In order to support this claim, there are many factors that must be addressed. I first clarify what pornography entails by exploring how it is conceptualised, what pornography ‘does’, and what it means to be a pornography consumer. Secondly, I examine the conceptualisations of substances, substance consumption and addiction, respectively, as well as the subsequent difference between substance and behavioural addiction. Thirdly, I give an inclusive overview of pornography addiction by not only examining the most recent perspectives of researchers, but also of pornography consumers. I conclude by suggesting how we should go about conceptualising pornography addiction, and then propose how the set of diagnostic criteria for pornography use disorder should be formulated for a future iteration of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders. I argue that, given the abundance of academic research on substance addiction, compared to the scarcity of research on behavioural addiction, conceptualising pornography as an addictive substance is more likely to create a sense of urgency for the future research of pornography addiction than would be the case if it is considered a potential behavioural addiction. Furthermore, I argue that the classification of pornography as an addictive substance, and the inclusion of pornography use disorder in a future iteration of the DSM, will raise awareness of the potential adverse effects of pornography consumption and, therefore, the harmful consequences of pornography use disorder.

The modern social world is unjust. It is also complex. What does this latter fact imply about the kind of approach that should be used in ameliorating the injustice expressed in the former fact? One answer, recently put forth by Jacob Barrett, is that _ideal theory_, which he understands as being fundamentally defined by the identification and subsequent pursuit of an aspirational macro-level institutional goal, lacks a place in social reform. The reason he thinks ideal theory lacks a place has (...) to do with its inability to deal with complexity. _Pace_ Barrett, I argue that ideal theory, suitably understood, can play a valuable role in social reform in a complex world. While some ideal theorists have underappreciated the extent to which complexity considerations complicate social reform, this does not mean that there is no place for it. This paper surveys the resources ideal theory has available to cope with what I call _the challenge of complexity_. Although the coping techniques will be successful to varying degrees, I believe, in aggregate, a compelling case can be made that ideal theory can combat the challenge of complexity. Still, one may worry that even if ideal theory can adequately deal with complexity, it cannot adequately deal with ever-changing social circumstances. Call this _the dancing landscape objection_. A static ideal theory cannot overcome it, but a _dynamic ideal theory_ could. In sum, dynamic ideal theory can contribute to social reform in a complex and mutable social world. (shrink)
