"Our erected wit maketh us to know what perfection is"

This quote by Philip Sidney speaks to the power of human intelligence and the capability of our minds to understand what excellence is. He is suggesting that our psychological faculties, or "set up wit," give us the capability to recognize and appreciate perfection. This indicates that perfection is not something that is simply fundamental in the world, but something that we can acknowledge and pursue through our own understanding. Sidney is suggesting that our minds can acknowledging and appreciating the greatest level of quality, and that this is something that we must pursue. He is motivating us to use our intelligence to recognize and value excellence, and to aim to attain it in our own lives. By doing so, we can reach our greatest capacity and live our best lives.
