All I am doing is trying to work out what the passages you quoted actually mean. I cannot work out what "focus" is supposed to mean the way your father used it.
The only way I can make sense of it is if it means "to look at" or "To direct attention to", but even then there are passages where this is problematical, and some of it becomes a bit circular. |
It's more than directing attention to, or looking at. How can a baby look at an object if he cannot focus because his eyes are not working in unison?

No, the eyes don't redirect light; they focus on the object just like we do in the afferent account. The only difference is that the baby could not focus until the other senses caused a desire to see.

Because I'm not done yet. After I'm done, you can either find his reasoning convincing, or you won't. It really doesn't matter to me, but you have to give him a chance to explain what he believed was going on.
