Paul Henry Smith, who can be contacted at his site here, raises several of the most important issues of philosophy in his post on Shostakovich, Pletnev and Bernstein. As these affect music, art, and many other questions, and are fundamental to issues dealt with in this blog, the following post deals with some of them. Paul Henry Smith is clearly able explain his own views so this 'comment on his comment' is only mine.
The first issue involved is what is in technical philosophical terminology 'ontological monism' - put non- technically it means that there is only one realm of reality and not more than one. To understand the implications of this consider some non-monist philosophies.
A classic example is Descartes - who held there were two different realities, 'mind and matter' or 'spirit and matter'. This is a dualist philosophy - i.e. one with two fundamental realities.
To take another example, Kant distinguished between 'phenomena', the world as it is perceived, and 'noumena', the world as it actually is (the 'thing in itself).
Non-monist philosophies lead to well known and impossible philosophical contradictions.
Descartes and his followers, for example, could not answer the question of how these two realms were supposed to interact, or the causal relation between them - arriving at the bizarre conclusion this interaction between matter and spirit took place through the pineal gland! Kant claimed that there could be no knowledge of 'the thing in itself' but simultaneously contradicted himself by claiming to have a crucial piece of knowledge about it - namely that it existed!
Monist philosophies were put forward by the ancient Greeks and in Asian philosophies. However in post-renaissance Europe Spinoza was the philosopher who first decisively put forward a monist conception of the world.
Naturally most people do not study, adhere to or even know about philosophical systems. But nevertheless philosophical viewpoints are built into parts of language or particular views put forward.
One concept, which both the original post on Shostakovich and Paul Henry Smith refer to, is that there is some 'spirit' of a work separate from what actually exists in the score, or in the play, or the painting. Another example is the frequent suggestion by Frederic Jameson, for example, that what has to be looked for is the 'essence' of a work of art - which is apparently separate from what actually exists in sight, or in sound etc. A further typical example may be found in a book such as Surface and Depth by Richard Shusterman. These frequently implicitly conceive that there is some 'spirit', or 'essence' or 'depth' which is separate from what actually exists.
Such a view is wrong. There is no such separate realm separate from what actually exists - whether as sound or visually or any other form. This does not mean that terms such as 'essence' cannot be used but they do not refer to anything which has a real existence separate from the actually existing.
Any philosophy course immediately makes the point that (pace Plato) there is no 'essence of whale' or 'concept of whale' existing separately from actual whales. There is equally no 'spirit' of Beethoven's Eroica symphony.
A second issue Paul Henry Smith deals with is that the observer, or in this case the listener, of course imposes their own order on that reality. He deals with the example of how we hear the interval of 'a fifth' in music. But we could equally take many other examples - that is there is no 'naive' perception of reality. An order is always imposed on reality by the observer/listener.
These issues have many implications a number of which are considered in this blog.
