The Renaissance (maximum flourishing 15th and 16th century) was a period that saw, in Europe, the birth of a new awareness of the greatness of the "ego", which was interpreted as the individual capacity for greatness - not as the selfish side of the self, as we understand it today. The human being was then seen and praised as a creature of value, capable of expressing himself in ways that would soar to fantastic heights in the artistic, scientific, intellectual fields (a few examples: Leonardo, Michelangelo, Shakespeare, Galileo etc.). The "I" was considered a source of spiritual growth.
Also today we are witnessing a renewed triumph of the "ego". How does it manifest itself? Mainly in talking no-stop about one's self, posting the so-called "selfies" and twitters, practically showing off all the time. In a nutshell, inventing more or less questionable ways to attract attention. What a difference!
