Bad or good

We live in a world in which our primary food is the information. We perceive the outside world through images, and each image has an echo in our brain, generating feelings, attitudes and sometimes questions.
Although we belong to the same specie, thousands of differences or similarities divide and classify us. Each of us perceives in his own way the information he receives. For some of us, something could be beautiful, for others the same thing could be ugly. Behind these two words, beautiful and ugly, we can see another words or, better said, concepts: good and bad. But what do good and bad mean? Do they really exist?
On one hand, good and bad are two words that express our opinion in terms of perceived images. We give the images values, which can be, as I already said, good or bad. On the other hand, being so many types of human beings, it is normal to be different kinds of perception and interpretation of information. Therefore, having many people who can interpret things in different ways, it is difficult for somebody to say what is good or bad, and in the same time to have his opinion shared by everyone. Trying to classify, we might come up with a result that might be true or not, depending on the point of view. In other words everything is relative.
Paradoxically, when we start thinking we, we discover that we actually know almost nothing, or that there are many things left, to be known. On the other hand, the more we know, the more we want to know. This desire of knowing more and more might be expressed through questions.
One big difference that separates the human beings from animals is that people ask themselves, why do we exist? and animals do not. If animals asked themselves this question, in that moment they would become human beings. If someone find an answer to this question, many things would be simplified. Our secret of life would not be a secret anymore. However, answering this question is difficult, maybe impossible. What we can do is to wait and think. Time will answer us.
