"What is good? All that heightens the feeling of power, the will to power, power itself in man"

In this quote, Friedrich Nietzsche is suggesting that what an individual thinks about to be "great" is anything that increases their sense of power or their desire for power. He thinks that this desire for power is inherent in all people which it is a basic element of our nature. For Nietzsche, power is a crucial part of being human and ought to be welcomed and pursued rather than rejected or suppressed.
