When I was born, I did not know the difference between right and wrong. Now, I do. The word philosophy means 
            
 the love of knowledge. One type of knowledge is propter quid, which ask the question why or how. In this paper, I 
            
 will demonstrate how Socrates, Hume and Aristotle, three well known philosophers, would explain how I acquired 
            
 this knowledge in relation to the principles of right and wrong. 
            
 Socrates is the  first philosopher, I will discuss. Since Socrates did not write anything down, Socrates thinking is told 
            
 through his student, Plato, who wrote his teachers' thoughts. Socrates is an idealist who believes that things are in

 or recollection. What the mind or soul once knew is raised to present awareness by a process of recollection aided by 
            
 the technique of dialect or the Socratic method. (Stumpf 260)
            
 This is known as the theory of recollection. The theory of recollection is told through Plato in the Phaedo and the 
            
 In the theory of recollection "Socrates' answer to the paradox is that knowledge is recollection. This thesis allows a 
            
 man to have ideas of which he later becomes conscious by recollection; thereby overcoming the sharp division 
            
 between not-knowing and knowing, and justifying inquiry." (Sternfeld, 35) Socrates states in the Meno " A man 
            
 cannot inquire about what he knows, because he knows it, and in that case he ...
