Skepticism is the philosophical position that all knowledge is unreliable. Skeptics argue that there is no way to know anything for certain, and that all of our beliefs are ultimately based on faith or opinion.

Pyrrhonian skepticism is a more radical form of skepticism than Academic skepticism. Pyrrhonian skeptics argue that it is impossible to know anything for certain, while Academic skeptics argue that it is only impossible to know anything for certain about the external world.

The main argument for skepticism is the argument from illusion. This argument points out that our senses can deceive us, and that we can therefore never be sure that we are perceiving the world accurately.

The main response to the argument from illusion is the argument from common sense. This argument points out that our senses are generally reliable, and that we can therefore trust them to give us accurate information about the world.

The main argument against skepticism is the argument from coherence. This argument points out that our beliefs about the world are generally coherent, and that this coherence is evidence that our beliefs are true.

The main response to the argument from coherence is the argument from skepticism. This argument points out that our beliefs about the world are often inconsistent, and that this inconsistency is evidence that our beliefs are not true.

The main argument for anti-skepticism is the argument from pragmatism. This argument points out that our beliefs about the world are useful for us, and that this usefulness is evidence that our beliefs are true.

The main response to the argument from pragmatism is the argument from skepticism. This argument points out that our beliefs about the world are often harmful to us, and that this harmfulness is evidence that our beliefs are not true.

The main conclusion of the debate between skepticism and anti-skepticism is that the debate is irresolvable. There are strong arguments on both sides of the debate, and there is no easy way to determine which side is correct.

Skepticism implies that we should only believe things that are probable. This is because skeptics argue that it is impossible to know anything for certain.

Anti-skepticism implies that we should believe things that are probable. This is because anti-skeptics argue that it is possible to know things for certain, but that we should only believe things that are probable.

Epistemic reliability is the degree to which a belief is likely to be true, while epistemic justification is the degree to which a belief is supported by evidence. A belief can be epistemically reliable even if it is not epistemically justified, and a belief can be epistemically justified even if it is not epistemically reliable.

All of the above factors contribute to epistemic reliability. The accuracy of our senses helps us to perceive the world accurately, the reliability of our memory helps us to remember things accurately, the coherence of our beliefs helps us to avoid contradictions, and the pragmatism of our beliefs helps us to avoid beliefs that are harmful to us.

All of the above factors contribute to epistemic justification. The evidence that supports our beliefs helps us to justify our beliefs, the reasons that we have for our beliefs help us to justify our beliefs, the coherence of our beliefs helps us to avoid contradictions, and the pragmatism of our beliefs helps us to avoid beliefs that are harmful to us.

Epistemic reliability is a necessary condition for epistemic justification. This is because a belief cannot be justified if it is not likely to be true. However, epistemic justification is not a necessary condition for epistemic reliability. This is because a belief can be reliable even if it is not justified.
