Seeing Straight in Front of You

It is common to talk about the direction of vision, visual direction, or line of sight, and in general where things are located visually. It seems right to say that things seem to be located in a particular visual way to the seeing subject. In addition, there is a particular direction to this appearance, in that some things can be said to be visually off to the side or straight in front of the seeing subject. However, I have problems with deciding what actual or real direction should be used to evaluate this visual appearance. A consequecne of these problems is I can only find bad reasons to hold that a visual appearance of direction is inaccurate.

This is a discussion about vision and space, not vision and time. But I think that what I’m going to say here relates to both. The issues for vision and space are very similar to issues for vision and time. The difference is that, for many theorists, time has a direction in a way that space does not.
