The Qualia Problem Multiple Choice

. The "qualia problem" that this reading refers to is that

You can never know if the red you see is the same as the red someone else sees.

Our understanding of the world is limited by our human senses.

It is hard for a dualist view of the world to account for qualia.

It is hard for a physicalist view of the world to account for qualia.

. Why does Jackson use the names "red-1" and red-2"?

The character Fred sees two colors where everyone else just sees the color red.

The character Fred is red-1/red-2 color-blind.

Jackson is imagining that we had named some other color "red."

Jackson is referring to the color red in two alternate universes.

. Scientists study all the physical information about Fred's optical system and brain. Finally, Jackson concludes that

Our scientific learning is still limited by our own limited brains.

We still won't know what it's like to see what he sees.

We still won't have the ability to distinguish red-1 and red-2 ourselves.

We will know everything there is to know about Fred's vision.

. What is unusual about the character Mary in Jackson's story?

She has extra-good color vision.

She is a scientist.

She donates her body to science.

She has lived her whole life in a black-and-white room.

. The main point of the Fred and Mary cases is that

Physicalism is incomplete; learning all the physical facts doesn't mean learning all the facts.

Physicalism is true; learning all the physical facts is enough to understand the cases.

The neurosciences have more explanatory power than dualism.

Qualia such as color experiences have no connection to what happens in one's brain and body.

. The view Jackson argues for in this reading is that the quality of experiences, such as seeing color,

Is different for different people.

Can't be explained by substance dualism.

Can't be explained in merely physical terms.

Can't be explained by today's neuroscience.

. In the previous reading, Nagel asked "What Is It Like to Be a Bat?" and commented that we cannot know what it is like. Based on these two readings, would Jackson and Nagel agree or disagree? Why?

Agree. We can learn all the physical facts about bats, but don't know what it is like to be one.

Agree. We can understand the experiences of bats and humans by looking at their brains.

Disagree. It's a lot easier to learn all the physical facts about bats than about humans.

Disagree. We know what it's like to be humans, but not what it's like to be bats.
