List of philosophical problems
This is a list of some of the major problems in philosophy.
A counterfactual statement is a conditional statement with a false antecedent. For example, the statement "If Joseph Swan had not invented the modern incandescent light bulb, then someone else would have invented it anyway" is a counterfactual, because, in fact, Joseph Swan invented the modern incandescent light bulb. The most immediate task concerning counterfactuals is that of explaining their truth-conditions. As a start, one might assert that background information is assumed when stating and interpreting counterfactual conditionals and that this background information is just every true statement about the world as it is (pre-counterfactual). In the case of the Swan statement, we have certain trends in the history of technology, the utility of artificial light, the discovery of electricity, and so on. We quickly encounter an error with this initial account: among the true statements will be "Joseph Swan did invent the modern incandescent light bulb." From the conjunction of this statement (call it "S") and the antecedent of the counterfactual ("¬S"), we can derive any conclusion, and we have the unwelcome result that any statement follows from any counterfactual (see the principle of explosion). Nelson Goodman takes up this and related issues in his seminal Fact, Fiction, and Forecast; and David Lewis's influential articulation of possible world theory is popularly applied in efforts to solve it.
Physicalist approaches offer alternative solutions to the problem of counterfactuals within a materialist framework. The interventionist account, developed by philosophers like James Woodward, solves the problem by defining counterfactuals in terms of specific physical interventions on causal systems. For example, "If Swan had not invented the light bulb" is interpreted as "If we intervened on the physical system to prevent Swan's invention". This approach avoids contradictions by clearly separating the intervened system from background conditions.
Another solution, proposed by Barry Loewer, uses statistical mechanics to ground counterfactuals. This approach defines the truth of counterfactuals based on the most probable evolution of physical microstates consistent with the counterfactual assumption. It resolves the initial problem by replacing abstract possible worlds with concrete physical probabilities, thereby avoiding logical contradictions within a physicalist framework.
Plato suggests, in his Theaetetus (210a) and Meno (97a–98b), that "knowledge" may be defined as justified true belief. For over two millennia, this definition of knowledge was accepted by subsequent philosophers. An item of information's justifiability, truth, and belief were seen as the necessary and sufficient conditions for knowledge.
However, in 1963, Edmund Gettier published an article in the journal Analysis, a peer-reviewed academic journal of philosophy, entitled "Is Justified True Belief Knowledge?" which offered instances of justified true belief that do not conform to the generally understood meaning of "knowledge." Gettier's examples hinged on instances of epistemic luck: cases where a person appears to have sound evidence for a proposition, and that proposition is in fact true, but the apparent evidence is not causally related to the proposition's truth.
In response to Gettier's article, numerous philosophers have offered modified criteria for "knowledge." There is no general consensus to adopt any of the modified definitions yet proposed. Finally, if infallibilism is true, that would seem to definitively solve the Gettier problem for good. Infallibilism states that knowledge requires certainty, such that, certainty is what serves to bridge the gap so that we arrive at knowledge, which means we would have an adequate definition of knowledge. However, infallibilism is rejected by the overwhelming majority of philosophers/epistemologists.
Physicalist and materialist approaches to the Gettier problem generally attempt to ground knowledge in causal or reliabilist terms, avoiding appeal to abstract justification. For instance, the causal theory of knowledge, proposed by Alvin Goldman, suggests that for a belief to count as knowledge, it must be caused by the fact that makes it true. This approach aims to solve Gettier cases by requiring a direct causal connection between the truth and the belief. Similarly, reliabilist theories, such as those developed by Goldman and others, define knowledge in terms of beliefs produced by reliable cognitive processes. These physicalist perspectives attempt to sidestep the traditional justification requirement that led to Gettier problems, instead focusing on the physical and cognitive mechanisms that produce true beliefs
