Are some organisms more sentient than others? Recent attention within animal welfare research centres around which and how much evidence is sufficient to ascertain whether a species' members are sentient. However, as more species are recognised as potentially sentient, a pressing issue arises in policymaking: should all sentient species be regarded as sentient to the same extent? While a degreed notion of sentience has been criticised as conceptually implausible or ethically problematic, this paper argues that these objections are flawed. By employing formal semantic tools, this paper proposes a delineation of the multidimensional structure of sentience that can serve as the basis for a framework for responsibly comparing degrees of sentience across species. The framework proposed underscores that the current debate regarding cross-species comparisons will only progress through an overall understanding of the different commitments that achieving welfare comparisons involves within the science-policy interface.

This paper explores nicknaming practices, focusing on their capacity to derogate and establish power differentials within a group. By examining ethnographic and psychological data, this paper contends that pejorative nicknames can contribute to unjust intra-group hierarchies and thus operate analogously to slurs within small social circles. Like expressions targeting social groups based on gender or ethnicity, pejorative nicknames can indeed elicit deep offence regardless of the speaker’s intentions or whether they occur within speech reports. Moreover, this paper advances a framework suggesting i) that both forms of verbal aggression index multiple dimensional qualities such as “negative valence”, “neutral arousal,” and “high dominance” rather than discrete emotional categories such as “contempt” or “anger”, and ii) that the expression of high dominance in social interactions underlies their capacity to offend. Additionally, it translates this hypothesis into a Bayesian model of sociolinguistic variation inspired by Heather Burnett’s work on identity construction, thus integrating pragmatic reasoning into a psychologically informed framework for interpreting emotional cues.

This paper argues that all-purpose pejoratives such as ‘jerk’ or ‘bastard’ are just plain vanilla descriptions of personality traits that are generally seen as impairing for the self and for interpersonal relationships across different contexts. Thus, all-purpose pejoratives derogate their referents through generalized conversational implicatures: it is common knowledge that those who use these terms accept certain kind of (negative) evaluations and that uses of those terms express such evaluations. One of the main advantages of this approach is that it can be extended to more ‘thick’ pejoratives such as ‘wimp’ or ‘chicken’, which, as Kaplan (1998) himself suggested, are ‘purely descriptive’ of personality traits that are generally seen as ‘personal failings’. Before defending this theory, I criticize i) the standard assumption that allpurpose pejoratives are expressive and ii) the alternative semantic view that allpurpose pejoratives are conventionally associated with a judge parameter.

This paper critically examines the philosophical underpinnings of current experimental investigation into animal affect-related decision-making. Animals’ affective states are standardly operationalised by linking positively valenced states with “approach” behaviours and negatively valenced states with “avoidance” behaviours. While this operationalisation has provided a helpful starting point to investigate the ecological role of animals’ internal states, there is extensive evidence that valenced and motivational states do not always neatly align, namely, instances where “liking” does not entail “wanting” (and vice versa). To address this limitation, this paper proposes the (re-)integration of dominance as a dimension of affect. In particular, I argue that dominance, construed as a measure of organisms’ self-assessed behavioural control, can provide the necessary nuance to understand animal affect-related decision-making. Thus, after addressing the theoretical and methodological challenges related to incorporating dominance into a definition of “core affect”, this paper introduces the “Valence-Arousal-Dominance” model of animal affect. This model is explored for its potential applications in two domains. Firstly, in the study of animal affect-related decision-making under predation risk, and secondly, in the study of animal wellbeing. Through these applications, this model aims to bring experimental paradigms of animal affect-related behaviour closer to ecologically relevant scenarios.

Swear words are highly colloquial expressions that have the capacity to signal the speaker's affective states, i.e., to display the speaker's feelings with respect to a certain stimulus. For this reason, swear words are often called 'expressives'. Which linguistic mechanisms allow swear words display affective states, and, more importantly, how can such 'affective content' be characterized in a theory of meaning? Even though research on expressive meaning has produced models that integrate the affective aspects of swear words in a compositional framework, there is extensive evidence that swear words cannot be assigned a single or stable affective interpretation across contexts. For example, even though expletive adjectives (e.g., 'damn'), particularistic insults (e.g., 'bastard') and slurs (e.g., 'wop') typically express (and elicit) negatively valenced affective states, they can also be interpreted positively in some contexts. Thus, inspired in recent developments in formal sociolinguistics, I propose an 'indexical' approach to affective meaning. Under this approach, an affective expression is associated with a set of affective qualities, anyone of which may emerge at a given context depending on the interpreter's prior assumptions about the speaker's affective states and/or relation with the target of the swear word. To define this set, also called 'indexical field', I will use the dimensions pleasure, arousal and dominance, standardly employed in cognitive psychology to characterize and measure affective episodes. In this dissertation, thus, the affective meaning of an expression is given by the set of affective states it typically conveys within a linguistic community, but its interpretation at a given context is established by taking into account the interpreter's prior assumptions about the speaker's affective states and/or attitudes with respect to the target of the affective expression.

Slurs’ meaning is highly unstable. A slurring utterance like ‘Hey, F, where have you been?’ (where F is a slur) may receive a wide array of interpretations depending on various contextual factors such as the speaker’s social identity, their relationship to the target group, tone of voice, and more. Standard semantic, pragmatic, and non-content theories of slurs have proposed different mechanisms to account for some or all types of variability observed, but without providing a unified framework that allows us to understand how different contextual factors simultaneously influence slurs’ interpretation. To address this issue, I argue that slurs convey dimensional qualities such as, e.g., ‘negative valence, neutral arousal, high dominance’ instead of discrete emotional categories such as ‘contempt’. Then, I translate this hypothesis into a game-theoretic model of slurs’ interpretation inspired by Heather Burnett’s pioneering work on identity construction. This new model, called ‘Affective Meaning Games’ (AMG), captures the variability of slurs and integrates pragmatic reasoning within an independently motivated psychological understanding of emotional states.
