In this paper, I ask what is wrong with sufficiency. I formulate a generic sufficiency principle in relation to which I discuss possible problems for sufficientarianism. I argue against the arbitrariness–concern, that sufficiency theory need only to identify a possible space for determining a plausible threshold, and I argue against the high–low threshold dilemma concern, that multiple-threshold views can solve this dilemma. I then distinguish between currency-pluralist and currency-monist multiple-threshold views and test them against two different versions of the widely shared ‘ignorance of inequality objection’ to sufficientarianism—a benefit-driven and a burden-driven version. I argue that currency-pluralist sufficiency views are better capable of responding to the former than currency-monist views. However, I show that no existing sufficiency view can provide a plausible response to the burden-driven version. Hence, I conclude that the problem of unequal distribution of burdens above the thresholds represents an overlooked threat to the sufficiency view, in any version.

This article claims that the protection of children’s capability for play is a central social-political goal. It provides the following three-premise argument in defense of this claim: we have strong and wide-ranging normative reasons to be concerned with clusters of social deficiency; particular fertile functionings play a key role for tackling clusters of social deficiency; and finally the capability for childhood play is a crucial, ontogenetic prerequisite for the development of those particular fertile functionings. Thus, in so far as we consider it a central political goal to tackle social deficiency, we should be concerned with protection of childhood play capability. This conclusion raises new insights on the importance – for global development policy as well as for welfare states’ aim to secure social justice – of protecting children’s capability to engage in playful activities.

Since his contribution to the field of personal identity in 1738 Hume’s theory has been debated thoroughly. Throughout the years there have been multiple critiques of Hume’s theory, but despite the fact that all of these generally appear unsatisfactory, Hume’s theory of personal identity is far from being a popular one in the field. I believe the blame partly falls on Hume himself. Hume’s appendix to Treaties is most often read as expressing a deep concern regarding his own theory, and this concern, I believe, is to blame for his theory never gaining the respect it deserves. After all, why should we listen to Hume if he himself found his theory lacking? It is, however, a mistake to judge Hume’s theory of personal identity, based on the appendix to Treaties. The appendix is far too ambiguity for any real conclusion and it offers nothing that cannot be found in the original chapter on personal identity from Treaties.
