Five mental components of human intentionality are distinguished and related to different properties of mammalian orientation. It is proposed that, in the course of evolution, these old properties became integrated and thereby allowed for the development of a new quality: human orientation. The existence of more than 4,000 mammal species with their various forms and levels of mental organization, offering a panorama of different combinations of differently developed components of mentality, provide ample opportunities for comparative studies. The difficulties in assessing (...) specific types are outlined, drawing on over 40 years of observation. Based on this knowledge, an argument is made for the importance of staying in contact with the empirical objects and of considering their ontological status when rising the standards of precision of formal analysis.

In a series of classic papers, Donald Davidson put forward an ingenious argument to challenge the ascription of minds to nonlinguistic animals. Davidson's conclusions have been mercilessly demolished in the literature by cognitive ethologists, but none of them have directly addressed Davidson's argument. First, this paper is an attempt to elucidate and evaluate Davidson's central argument for denying minds to nonlinguistic animals. Davidson's central argument puts forth a challenge to those of us who want to attribute minds to nonlinguistic animals. (...) Second, this paper uses counterexamples offered in the cognitive ethology literature to meet Davidson's challenge directly. (shrink)

A common Western assumption is that animals cannot be persons. Even in animal ethics, the concept of personhood is often avoided. At the same time, many in cognitive ethology argue that animals do have minds, and that animal ethics presents convincing arguments supporting the individual value of animals. Although “animal personhood” may seem to be an absurd notion, more attention needs to placed on the reasons why animals can or cannot be included in the category of persons. Of three different (...) approaches to personhood—the perfectionist approach, the humanistic approach, and the interactive approach—the third approach is the strongest. Personhood defined via interaction opens new doors for animal ethics. (shrink)

My dissertation addresses the question "do desires provide reasons?" I present two independent lines of argument in support of the conclusion that they do not. The first line of argument emerges from the way I circumscribe the concept of a desire. Complications aside, I conceive of a desire as a member of a family of attitudes that have imperative content, understood as content that displays doability-conditions rather than truth-conditions. Moreover, I hold that an attitude may provide reasons only if it (...) has truth-evaluable content. Insofar as desires lack truth-evaluable content, I hold that the content of a desire has the wrong kind of logical structure to provide reasons. My second line of argument claims that even if a desire did have truth-evaluable content, it would not follow that desires provide reasons. This is because a desire has no more rational significance than a guess or coin-flip. My argument relies on what I call the non-substitutability principle, the thesis that (all things being equal) one cannot substitute something that lacks rational significance, relative to some attitude, A, for something that has rational significance, relative to A, and leave the rational standing of A unchanged. For example, one cannot substitute the guess that P (i.e., something that lacks rational significance relative to the belief that P) for the perception that P (i.e., something that is rationally significant relative to the belief that P) without altering the rational standing of the belief. I argue that when the non-substitutability principle is applied to a desire that gives rise to an intention, it turns out that one can always substitute a guess or coin-flip (i.e., something that lacks rational significance relative to the intention) for the desire, without altering the rational standing of the intention. I take this to show that desires are not rationally significant relative to the intentions to which they give. (shrink)

External descriptions, which approach animals via external mechanisms rather than internal mental states, have gained a prominent position. However, according to strong objectivism, attention needs to be placed on the presumptions that lay behind given beliefs. When applied to the topic of animal minds, it reveals that perhaps inter-nal rather than external descriptions would offer a fruitful option. This claim is sup-ported by the Wittgensteinian criticism of skepticism, which seeks to avoid “deflection” and brings forward an “affective stance”. Still, in (...) order to avoid relativ-ism and conservatism, internal descriptions and the affective stance need to place em-phasis on the epistemological ramifications behind beliefs concerning animal minds, and centralise the animal as the reference point of inquiry.
