According to radical constructivism reality is a product of experience. When individuals have the same experiences a shared reality is formed for society. The possibility of an object having properties that humans cannot perceive is enough for Von Glaserfeld to say that we cannot understand what constitutes "real" objects. I feel that the possibility for objects to have more properties than we can potentially imagine does not hinder humans to fully understand them. Since all humans are incapable of perceiving such characteristics then no one has an advantage over anyone else and our shared reality is not threatened. If everyone as a society is faced with the same limits of knowledge then why can't we view our realities and the objects that construct them as "real." After all, they are as "real" as we will ever understand them to be.
