What is reprehensible is that while leading good lives themselves and abhorring those of wicked men, some, fearing to offend, shut their eyes to evil deeds instead of condemning them and pointing out their malice.
If optimism is important, it's because many outcomes are determined by how much of it we bring to the task. It is an important ingredient of success. This flies in the face of the elite view that talent is the primary requirement of a good life, but in many cases the difference between success and failure is determined by nothing more than our sense of what is possible and the energy we can muster to convince others of our due. We might be doomed not by a lack of skill, but by an absence of hope!
The good lawgiver should inquire how states and races of men and communities may participate in a good life, and in the happiness which is attainable by them.
When several villages are united in a single complete community, large enough to be nearly or quite self-sufficing, the state comes into existence, originating in the bare needs of life, and continuing in existence for the sake of a good life.
I myself feel, and also tell other Buddhists that the question of Nirvana will come later.
There is not much hurry.
If in day to day life you lead a good life, honesty, with love,
with compassion, with less selfishness,
then automatically it will lead to Nirvana.
