"There are three classes of people: those who see. Those who see when they are shown. Those who do not see. "
- Leonardo da Vinci

     Humans have a tendency to feel the need to categorize everything, but why? This sense of belonging may have to do with the ego's desire to become something more greater, enlarging our identity beyond individualism; it's something that can't be done by a mere individual alone but rather a group that will make an impact. After analyzing the society that surrounded him, Leonardo da Vinci concluded that humans are classified into three categories: people who see, those who see once shown and those who don't see at all. Basically he places individuals into three categories of people who are artistic, anxious and average.
     The artistic ones are people with a goal, focused on that goal and having the confidence to pursue that goal due to their acceptance of themselves, a clear vision and drive of where they are headed. Those who must be shown in order to see are the anxious people. These are the types of people who have trouble expressing their own wishes due to inner and external conflict. Leonardo's blind category consists of those who conform their will to external forces, the majority of people. When encountering people through life we constantly run into people who fit under these categories depending on the circumstances. For instance if I'm given a assignment to draw a still life I would easily would be a person who sees who has a full vision of what to draw and where the source of light is coming from , I would be able to visualize it all, but as soon as the assignment shifts to using three watercolors to create an entire photo that confidence level I once had will begin to decrease and my the inner conflict of doubting myself will appear. Probably causing me to need someone to show me in order for me to see.
    
     And then there's the interpretation of humans classified into three categories of people's level of ignorance. Starting from the people who see( those of us that are intuitive) to people who see once shown (open minded) and then there's those who don't see( ignorant people).Unlike the previous interpretation these are generally fixed trait of a person's personality and their perception of the world.
     For example there are gurus (Sanskrit for master) who are beacons of spiritual light in our world eliminating the darkness of ignorance and bringing light with knowledge. Through this understanding of extinguishing this darkness with light they go through a realization that god is knowledge which is within themselves. These people would be the ones who see then spreading their newly found knowledge to those who must be shown in order to see, in this case would be their followers. Eventhough these people must be shown, their willingness to be open minded allows them to obtain knowledge, they are equally wise. Through perseverance they to can reach this state because they were willing to give something a chance and experience for themselves based on whether or not they believed the knowledge they attained. And then we come to those who see their teachings as complete ludicrous, the ignorant ones; the ones who are closed minded, the ones who lack the general knowledge of other teachings, the ones who based on no understanding make a conclusion, the ones who refuse to hear the other side out. At the same time religion is something that can be the complete opposite when dealing with the fanatics of a religion; those who see only their religion as the only way and refusing to hear others out.
      Da vinci made an peerless assessment of the human race's tendencies because no mater the way the reader perceives his assessment he classifies humans perfectly relating it to all; not a single person left out.
