You can set up a question, like 'How many sheep are in the field?', that isn't about any particular person's brain, and whose actual answer doesn't depend on any particular person's brain.

Then again, which field the phrase “the field” refers to does depend on who is asking the question where and when.

Judgments that depend on our representations of anyone's state of mind, like "It's okay to kiss someone only if they want to be kissed", are the exception rather than the rule.

Among all possible judgements, sure; but among all those judgements that a real person will have to make in the real world...
