It is evident that the mind knows not things immediately, but only by the intervention of the ideas it has of them. Our knowledge therefore, is real, only so far as there is conformity between our ideas and the reality of things. But what shall be here the criterion? How shall the mind, when it perceives nothing but its own ideas, know they agree with things themselves? So who is right? These are just three different views on reality out of hundreds, and possibly even thousands from other philosophers, but is there any one way to know if one philosopher’s theory is right over another? One thing most of these theories have in common is that our perceptions of reality, how we view things through our senses and the different objects we see, may not be what is certainly real, they suggest that what our perceptions of reality are, are not really what reality is. What this means is that for the average person living, their reality is based upon ignorance towards other truths. Throughout the span of humanity, we as a species have looked upon the workings of the universe through the lens of religion, using it to explain the unexplainable. However, secularized sciences began to surface and thus, scientific explanations began to replace religious beliefs. What was previously the affliction of ignorance towards the people who used religion to perceive the world around them transformed into a truth. However, as the sciences and technology grew more advanced, previous scientific theorems began to be disproved by newly discovered ones. Again, the ignorance transforms into truth; nonetheless, each and every time ignorance converts to truth new ignorance manifests. As an example in while inside the matrix, Neo had no idea that his reality was created by the workings of a machine. To him, the food he ate was real, and the punches he took in the face were painful. He perceived the mechanical world he resides in to be reality, to be real. However, as soon as he awakens to the new reality, outside of the machine, his previous life became an obsolete truth to him, and this new one became his new reality. Reality is a cycle of truth and ignorance, and will continue to be so eternally. Unless one is omniscient, there will always be a truth, a fact, in existence that will carry the potential to disprove everything we know.
