This is a type of ad hominem fallacy because you’re downvoting based on something about the speaker that is unrelated to the argument. You might argue that there is a correlation between the misspellings and logical fallacies, but you offer no evidence, and the fact that you committed this phallusy while spelling everything correctly speaks otherwise.

There’s a lot of assumptions in saying it’s just meaningless chemicals

• That chemicals are meaningless and lacking intriniic value. Seen from the outside they may appear that way, but evidently from the inside it seems quite different.
• “We” are not some other unseen brain behavior (not a crazy idea since we’ve never seen consciousness working in the brain)
• We are within the brain
• The brain exists at all
• Any knowledge exists at all (dubious as Mickey points out)

But then what perceives the illusion? How can the whole concept of an illusion have any meaning without a thinker to perceive what isn’t true?
