Common Sense: Our Innate Foundation of Knowledge
             The human brain, as we know it, was created within the parameters of metaphysical laws, which were then built into the architecture of the human mind. Using this theory as a premiss, one could hypothesize that the brain itself, recognizes the parameters of metaphysical law. Just as these laws proclaimed the undeniable truths behind concepts such as time and space, they establish the existence of an external world as did Moore through his use of common sense by saying, "here is one hand" and "here is another".

This however cannot be considered a definition of common sense; the issue of what common sense is vexed, and its vexedness is one reason why many philosophers eschew the word altogether. " (Wikipedia1) Moore believed that propositions are truer than premises because the premises or what Moore would "theories" claimed by some philosophers contain falsehoods. Moore believed it is more justified to believe in "common sense".
             Common sense is a part of our a priori knowledge, among many other undeniable facets of human knowledge. Human intuition includes axioms that coincide with common sense. Axioms are known only through human intuition, which are the part of our consciousness that Descartes refers to in his first meditation when he states "...the simplest and most general things, regardless of whether they really exist in nature or not, contain something certain things that are certain and indubitable". He went on to specify, " For whether I am awake or asleep, two and three added together equal five, and a square has no more than four sides".
