Apples and pears, originally uploaded by c.zwerg

Speaking of Post Structuralism, take a look at this demi-proof:

1. Take an apple.
2. The apple has an intrinsic apple-ness which all apples contain.
3. Similarly, a pear has a pear-ness which is distinct from the apple-ness apples contain.
4. Pears and apples might be fruit, but their intrinsic this-ness belong to the apple and pear, respectively.
5. Imagine a scientist who invents a method to grow an apple which looks like a pear, but tastes and exhibits all the intrinsic apple-ness of an apple.
6. Does the pear-apple have the same intrinsic apple-ness as a regular apple?
7. Does the pear-apple’s apple-ness also take on pear-ness? Or is the deep nature of the apple’s apple-ness unchanged by the transposition of visual context?
8. In other words, is the basic idea of an apple changed because it is in the shape of, and looks like, a pear?
