Concrete is real. Reality is abstract. ________________________________________________________ concrete (HARD MATERIAL) noun : a very hard building material made by mixing together cement, sand, small stones and water. reality noun : the state of things as they are, rather than as they are imagined to be, according to 6 billion people. ________________________________________________________

In programming terms, abstraction means regrouping certain concepts together. Concrete means an instance of this abstraction that has its own existence. Hence I would say reality is both concrete and abstract. For example, I can describe a pair of boobs with many different levels of abstraction, one of them could be 'a tool to feed mammals when they grow up', another could be 'a handle for all sorts of fun' Yet, breasts still exist in reality (unless they're not real ;P) so they are concrete.
