The question I have chosen to answer is: What is the difference between what is accidental and what is being a individual person? 
 
The difference between what is accidental and what is just being an individual person is that the accidental is unavoidable or inevitable. Being an individual person can be altered or changed by your surroundings. What is accidental to you can be the family you or class are born into or your genes and what is hereditary/genetic. If you're family has history of some kind of illness it may be impossible to avoid also having this certain illness. Being an individual person depends on and differs with the persons surroundings. The individual person describes who the person is regardless of any possessions or anything "accidental" that may have come to them. The person as an individual would more so tell who the person is, not by their status or their possessions, but by who they are regardless of all that. However if you think about it, a person, individually, is described and is who they are because of who they are and based on what they have. Unfortunately people change based on their status in life and their status is usually based on materially possessions and money. I believe that this is also comes into play when speaking of the "contradiction". How can someone be described and enveloped in material possessions or "accidental" examples when that should not be the basis of who they are.
