The metaphysical touch is to reality what an absolute ear is to music. If for example you strike a glass and you correctly recognize the sound as a B flat, you have an absolute touch. Those who do not have an absolute touch have a relative touch, and they consequently perceive essentially the intervals between the notes. For example, they hear in the same manner the series of three notes “do re mi” and the series of three notes “sol la si”: in both cases the intervals between the notes are the same. A metaphysical touch is therefore a type of absolute ear in the order of being, whereas a relative ear captures mostly modes, accidents and relations.
As willed, I have translated these musings for a friend ("Avatar" - R.I.P.) who started with philosophy at a very early age. I also entertain an interest in realist philosophy, albeit at a less advanced level. I'm quite happy to answer any comment in this area, to the best of my ability, and in the original spirit of the author - i.e. in the spirit of realistic thought.
