This paper argues that formal models of coherence are useful for constructing a legal epistemology. Two main formal approaches to coherence are examined: coherence-based models of belief revision and the theory of coherence as constraint satisfaction. It is shown that these approaches shed light on central aspects of a coherentist legal epistemology, such as the concept of coherence, the dynamics of coherentist justification in law, and the mechanisms whereby coherence may be built in the course of legal decision-making.

The concepts of omniscience and omnipotence are defined in 2 ? 2 ordinal games, and implications for the optimal play of these games, when one player is omniscient or omnipotent and the other player is aware of his omniscience or omnipotence, are derived. Intuitively, omniscience allows a player to predict the strategy choice of an opponent in advance of play, and omnipotence allows a player, after initial strategy choices are made, to continue to move after the other player is forced to stop. Omniscience and its awareness by an opponent may hurt both players, but this problem can always be rectified if the other player is omniscient. This pathology can also be rectified if at least one of the two players is omnipotent, which can override the effects of omniscience. In some games, one player's omnipotence ? versus the other's ? helps him, whereas in other games the outcome induced does not depend on which player is omnipotent. Deducing whether a player is superior (omniscient or omnipotent) from the nature of his game playing alone raises several problems, however, suggesting the difficulty of devising tests for detecting superior ability in games.

This paper aims to contribute to our understanding of the notion of coherence by explicating in probabilistic terms, step by step, what seem to be our most basic intuitions about that notion, to wit, that coherence is a matter of hanging or fitting together, and that coherence is a matter of degree. A qualitative theory of coherence will serve as a stepping stone to formulate a set of quantitative measures of coherence, each of which seems to capture well the aforementioned intuitions. Subsequently it will be argued that one of those measures does better than the others in light of some more specific intuitions about coherence. This measure will be defended against two seemingly obvious objections.

I will show that, in the Problem of Old Evidence, unless a rational agent has a property I will call theoretical omniscience (a stronger version of logical omniscience), a problem with non-commutativity of the learning theories follows. Therefore, scientists, when trying to behave as close to rationality as possible, should behave in a way close to the counterfactual strategy. The concept of theoretical omniscience will be applied to the problem of Jeffrey conditionalization, as an example, and we will see that a more complete theoretical model can provide a classical conditionalization where you can learn that data was wrong and all you will not unlearn is your memory.

This paper argues that the logical coherence of classical theism can be defended through the traditional free-will defense and argument from divine omniscience and human finitude, but only at the cost of moral scepticism. The above two-pronged defense entails moral scepticism because it demands that we construe clear and undeniable cases of morally unjustifiable evil as merely apparently unjustifiable evils which can be morally justified from some moral point of view. The paper argues that justification is impossible because such basic evils can never be justified from any "moral" perspective. The very conditions necessary for having a moral perspective demand that one recognize certain evils as unjustifiable from any moral point of view. This is the case because moral theories are designed to give us insight into such evils. Moreover, I argue that even if one rejects the above argument, moral scepticism still follows because any intelligible account of moral knowledge requires that its proponents be able at least to point to certain cases of unjustifiable evil if their theory is to have any purchase in the real world and avoid the charge of moral irrelevance and moral scepticism. But this is precisely what the classical theist cannot do. If, however, the classical theist rejects this moral scepticism, then real cases of morally unjustifiable evil must be admitted to exist and a single one of these is sufficient to undermine the logical coherence of classical theism.

There is an objection to coherence theories of knowledge to the effect that coherence is not connected with truth, so that when coherence leads to truth this is just a matter of luck. Coherence theories embrace falliblism, to be sure, but that does not sustain the objection. Coherence is connected with truth by principles of justified acceptance that explain the connection between coherence and truth. Coherence is connected with truth by explanatory principle, not just luck.

In contemporary philosophy of religion, the doctrine of omniscience is typically rendered propositionally, as the claim that God knows all true propositions (and believes none that are false). But feminist work makes clear what even the analytic tradition sometimes confesses, namely, that propositional knowledge is quite limited in scope. The adequacy of propositional conceptions of omniscience is therefore in question. This paper draws on the work of feminist epistemologists to articulate alternative renderings of omniscience which remedy the deficiencies of the traditional formulation.

This essay examines a conflict between God's omnipotence and His omniscience. I discuss our intuitions regarding omnipotence and omniscience and describe a method by which we can decide whether a being is omnipotent. I consider the most promising versions of omnipotence and argue that they produce a genuine conflict with omniscience. Finally, I suggest that we can take the example of omniscience and generalize it to several of God's essential properties and thereby reveal incompatibilities that result even from sophisticated conceptions of divine attributes.
