Depending on the definition, I disagree with 2. I agree that we have<br>
experiences as proven by brain scans when we're exposed to various<br>
experiences. So if instead of qualia, we'd say experiences, I have no<br>
quarrel with experiences or states in the brain being real.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">The reason I am led to the opinion that qualia are incommunicable is as follows:</div><div dir="auto"><br></div><div dir="auto">Let's say that a certain experience is the result of processing information in a certain ways.
