Angelou's "startling truth" is the fact that humans are this world's most beautiful and best treasure, and when people finally come to this truth all wars, violence, and hatred will be over. I agree with her based on three things. The first and third could be called subjective truths and the last reason I agree with Maya Angelou is based on an absolute truth.
The first reason I agree with Angelou is because I believe that if people would take care of others before themselves then the world would be a better place. If a person is on the street and hungry because they have nowhere to go then someone should help them either by taking them to a shelter or even taking them home, depending on a person's comfort level. If more people put other's needs first then there would not be as many needy people in this country and we could start focusing on how to help other countries with their poverty problems as well. My belief is a subjective truth because it is personally true for me and may not be true to anyone else.
The absolute truth behind my agreement with Maya Angelou is simple. If everyone thought everyone else was great and a person was more valued then something like oil or land then there would be no more killing. If there would be no more killing there would be no way to have a war. Likewise no one would go hungry because the world would be motivated by the human existence instead of a desire to satiate themselves first. I believe that this type of world is the kind that Angelou describes and this is absolutely true.
The third reason I agree with Angelou's truth is based on the truth that men were created in the image of God and the first man and woman were perfect. One of the reasons they were so perfect was because they were in such a relationship where God was number one and then the other person came first. Adam and Eve knew they were the best part of creation because God them dominion over all the creatures He had made. In short what Maya Angelou writes is the perfection of the Garden of Eden and the world to come. This may be called a subjective truth because it is not true for everyone, and it cannot be proven. To me, however, this truth is absolute.
The reasons I have given for agreeing to Angelou's "startling truth" are subjective and absolute. The first reason is because I believe in the value of people based on their own humanity. The second is because God made us in His image and when we get back to that everything will be good again. The third reason is because if people were valued more than things than there would be no violence, war, or hatred because a life would mean more than an object.
