Electronic Red Apples....

The electron is definitely not a human construction because this particle of matter would exist even if humans did not. Our perception of electrons is the differing element, no pun intended. What we think we see in an ES microscope and the roles we believe electrons play in matter and function of materials is what changes and makes it constructed in our minds and reality.

This is similar to my stance on the color red. I think if humans did not exist, the thing which we perceive as "red" would still be an occurrence in the world but could be called by another title by another organism, however it would still be the same object. I feel the same way about Apples, and most fruit in general. These plants are a part of nature and would continue to exist whether or not we cultivated them for specific purposes, like consumption. Another organism may call them by another name, or the fruit could be poisonous to other systems of anatomy, but the object itself remains constructed by nature.
