There is a structural similarity between an influential argument of Berkeley's against causal realism and a traditional, and recently revived, argument against the correspondence theory of truth. Both arguments chide the realist for positing a relation between his conceptions (perceptions) of reality and a world independent of those conceptions (perceptions). Man could have no epistemic access to such a relation, it is said, for, by the realist's own admission, he has access to only one of the relata - his conceptions (perceptions). I claim that the relation in question need be no more than that alleged by the biological and behavioral sciences to hold between organisms and their environments. And when studied as such, it reveals ways whereby the realist may claim to know of an outward correspondence solely on the basis of characteristics of one of the relata - his conceptions (perceptions).

Peacocke's characterization of what he calls implicit conceptions recognizes the significance of a subset of contentful states in making rational behavior intelligible. What Peacocke has to offer in this paper is an account of (i) why we need implicit conceptions; (ii) how we can discover them; (iii) what they explain; (iv) what they are; and (v) how they can help us to better understand some issues in the theory of meaning and the theory of knowledge. The rationalist tradition in which Peacocke's project ought to be located is concerned with the nature of understanding. His notion of implicit conceptions is invoked to explain non-straightforwardly inferential but rational patterns of concept-involving behavior. We come to know about implicit conceptions because we treat the thinker's practices as having a certain representational content. They are implicit in what the thinker does. I intend to focus on the question of what implicit conceptions are (although in doing so some of the other aspects will also come to the fore). I will argue for the following position: that —even at the personal level— certain inferential principles underlie the process that leads to the thinker's reliably differential responses and that subsequently point us in the direction of a notion such as that of an implicit conception. More precisely, I will argue that practical inferential processes are involved in the understanding-based capacities that support our ascription of personal-level implicit conceptions to the thinker. If I am right, then Peacocke's implicit conceptions don't preclude acceptance of personal-level conceptual role theories because that practical inferential articulation, i.e. that conceptual role, is the implicit conception itself.

This paper defends an interventionist treatment of mechanisms and contrasts this with Waskan (forthcoming). Interventionism embodies a difference-making conception of causation. I contrast such conceptions with geometrical/mechanical or “actualist” conceptions, associating Waskan’s proposals with the latter. It is argued that geometrical/mechanical conceptions of causation cannot replace difference-making conceptions in characterizing the behavior of mechanisms, but that some of the intuitions behind the geometrical/mechanical approach can be captured by thinking in terms of spatio-temporally organized difference-making information.

It is occasionally claimed that the important work of philosophers, physicists, and mathematicians in the nineteenth and in the early twentieth centuries made Kant’s critical philosophy of geometry look somewhat unattractive. Indeed, from the wider perspective of the discovery of non-Euclidean geometries, the replacement of Newtonian physics with Einstein’s theories of relativity, and the rise of quantificational logic, Kant’s philosophy seems “quaint at best and silly at worst”.1 While there is no doubt that Kant’s transcendental project involves his own conceptions of Newtonian physics, Euclidean geometry and Aristotelian logic, the issue at stake is whether the replacement of these conceptions collapses Kant’s philosophy into an unfortunate embarrassment.2 Thus, in evaluating the debate over the contemporary relevance of Kant’s philosophical project one is faced with the following two questions: (1) Are there any contradictions between the scientific developments of our era and Kant’s philosophy? (2) What is left from the Kantian legacy in light of our modern conceptions of logic, geometry and physics? Within this broad context, this paper aims to evaluate the Kantian project vis à vis the discovery and application of non-Euclidean geometries. Many important philosophers have evaluated Kant’s philosophy of geometry throughout the last century,3 but opinions with regard to the impact of non-Euclidean geometries on it diverge. In the beginning of the century there was a consensus that the Euclidean character of space should be considered as a consequence of the Kantian project, i.e., of the metaphysical view of space and of the synthetic a priori character of geometry. The impact of non-Euclidean geometries was then thought as undermining the Kantian project since it implied, according to positivists such..

What are the conceptual connections between torture and profession? Exploring this question requires exploring at least two others. Before we can work out the conceptual connections between profession and torture, we must have a suitable conception of both profession and torture. We seem to have several conceptions of each. So, I first identify several alternative conceptions of profession, explaining why one should be preferred over the others. Next, I do the same for torture; and then, I argue that, given the preferred conception of torture and the preferred conception of profession, there can be no profession of torturers. In the final section, I argue that deliberately torturing or aiding in torture is always unprofessional. The fact that some conceptions of profession do not yield this conclusion tells us more about the inadequacy of those conceptions than about professions.

Experiments with young infants provide evidence for early-developing capacities to represent physical objects and to reason about object motion. Early physical reasoning accords with 2 constraints at the center of mature physical conceptions: continuity and solidity. It fails to accord with 2 constraints that may be peripheral to mature conceptions: gravity and inertia. These experiments suggest that cognition develops concurrently with perception and action and that development leads to the enrichment of conceptions around an unchanging core. The experiments challenge claims that cognition develops on a foundation of perceptual or motor experience, that initial conceptions are inappropriate to the world, and that initial conceptions are abandoned or radically..

The starting-point is the distinction between concept and conception. Our conceptions of gold, for instance, are the different understandings we get when we hear the word ‘gold’ whereas the concept of gold consists in the scientific determination of what gold is. It depends on the context whether it is more reasonable to claim a concept or to look for fitting conceptions. By arguing against metaphysical realism and for non-metaphysical realism, I will elaborate on some philosophical reasons for dealing with conceptions instead of concepts of God, and secondly, I will discuss how such conceptions should be critically assessed.

• This comes from my general view of the nature of mathematics, that it is humanly based and that it deals with more or less clear conceptions of mathematical structures; for want of a better word, I call that view conceptual structuralism.
