We Do Not Choose to Be Born

We do not choose to be born. We do not choose our parents. We do not choose our historical epoch, the country of our birth, or the immediate circumstances of our upbringing. We do not, most of us, choose to die, nor do we choose the time or conditions of our death. But within all this realm of choicelessness, we do choose how we shall live: courageously or in cowardice, honorably or dishonorably, with purpose or in drift. (Joseph Epstein, Ambition: The Secret Passion) Aargument; conclusion: Within all this realm of choicelessness, we do choose how we shall live: courageously or in cowardice, honorably or dishonorably, with purpose or in drift.
