I was interested in this post from The Two Doctors which brings philosophy into the consideration of wine tasting. He writes of the philosophy of John Locke (1632-1704):
“Among Locke’s simple ideas is a distinction between those experiences that are primary qualities of objects and others that are secondary qualities. The distinction divides those qualities thought to be essential and inherent to all objects and those that are apparent only on account of the effect that the objects have on our senses. Primary qualities include solidity, shape, motion or rest, and number. Secondary qualities are those such as scent and taste. These are secondary because, according to Locke, they do not inhere/reside in the objects themselves, but are causally produced only in our minds by the effect of an object’s primary qualities upon our senses. Another way of conceiving them is to say primary qualities are objective (really exist) and secondary ones subjective (only exist in the minds of observers).”
This suggests an interesting point in history, where a judgement is applied to the inner/outer or subjective/objective polarity that lies at the heart of existence. In defining the objective (left brain) stuff as primary, and the subjective (right brain) stuff as merely secondary, Locke is applying a judgement that resounds in history, leading to the modern materialistic world and much denial of interiority and spirituality.
Locke could have expressed it the other way round, ie that the subjective is primary (really exists) and the objective merely secondary (only exists as a mental construct). This might have led to a world view where consciousness is seen as primary, rather than the material world. How different history might have been!
Of course, actually there’s no question of primary and secondary, we are speaking of two aspects of a fundamental polarity of existence.
