Hetero-phanomenology/HP/DennettVsBrentano/VsHusserl: hetero-phenomenology works from the perspective of the 3rd person instead of the first.
RadnerVsDennett: Thesis: hetero-phanomenology can also be operated from the first person perspective.

Hetero-phenomenology/Radner: hetero-phenomenology deals with:
1. How things appear to a subject
2. How is the experience of the subject ("how is it for the subject ...")?
Frank Jackson: treats both as equivalent:
E.g Fred: for him there are two red hues, where all the others only perceive one. How is it for Fred to see Red1 and Red2?
Radner: the question varies between (1) and (2).
In the first sense, Jackson: "How is the new color?"
In the second sense, Jackson: "if we could adapt our physiology to that of Fred, we would finally know."

Experiences.
E.g. M. Tye: instead of saying,
A) The color blind Jones does not know how the different colors look, we can just as well say,
B) He does not know what it is like to have the experiences characteristic of seeing the colors.
Both hang together, but problems are not always the established and reversed equally well in the sense of 1. as of 2.

For example, color researcher Mary/Jackson/Radner: the problem is not how red may look for Mary (probably as for us), but how her experience will be. Will it be a surprise?

Environment/Inner world/Radner: both can be approached from the viewpoint of the 1st and the 3rd person.

This distinction does not correspond to that between car and hetero-phenomenology.
Hetero-Phenomenology: 1., 3. Person/environment/inner world: all combinations of questions are possible.
Environment/hetero-phanomenological: 3rd person: E.g.: "How do things appear to the subject?"
1. Person: E.g. "How would things appear to me if I had a sense device like that of the subject?"
Inner world/hetero-phenomenological: 3rd person: E.g.: "How are the experiences of the subject?"
1. Person: E.g.: "How would my experiences be if I were in the circumstances of the subject and had certain characteristics in common with it?".

Hetero-phenomenology/Radner: E.g. he would like to know how a warning call sounds for another subject, e.g. for birds of prey like hawks or owls, which have a smaller head than us.

How would it be if I had no auricles and the ears were only two inches apart?
Problem: I may be able to imagine other ears on my brain, but not how it would be for me with a cat brain.
