Answering the Skeptic Yes, we do, but it doesn't follow from that that we're right. You're welcome to just commit to this acceptance and carry on with your life, but that hardly counts as a good philosophical defence of the position against alternatives (anti-realism, idealism, phenomenalism, etc.). — Michael
On the one hand you seem to agree that our perceptions are grounded without need for a justification, but then you add that "...it doesn't follow that we're right." It sounds contradictory. To show that one is right,
is to have some kind of justification, otherwise what would
being right in this context mean?
Basic beliefs (bedrock beliefs or hinge-propositions) are not the kind of beliefs that need any justification, i.e., it's not a matter of being right. They form the substrata of all of our epistemic justifications, i.e., without them we couldn't talk about being right or wrong. In a sense bedrock beliefs are like the rules of chess, i.e., without them one couldn't play the game. Reality is just there as a backdrop, similar to the rules of chess. Moreover, there is a causal link between our sensory perceptions and these very basic beliefs. A causal link between the world and our sensory perceptions that form bedrock beliefs. These are beliefs that are formed prior to language, and prior to our ability to talk about them in epistemic ways. They form the backdrop of all linguistic beliefs. You were right when you said that they are just beliefs, but they are very different from other kinds of beliefs, they are states-of-mind that are foundational to everything that follows from linguistic beliefs (knowledge, truth, etc). This is why they are outside the scope of what these questions of justification or being right are about.
These theories of reality that philosophers like to play with are worthless. There is no theory of reality that will capture the essence of what reality is, no more than one can capture the essence of what a
game is in a definition. In a sense one would have to get outside of reality, or outside of ourselves to understand some of these questions, or to make sense of the questions.
Propositions about reality are understood by understanding how these words are used, but it would be a misunderstanding to assume that use always drives meaning. Philosophers are notorious for using words in ways that violate normal usage.
