Beethoven’s music tends to move from chaos to order as if order were an imperative of human existence.

贝多芬的音乐往往从混乱走向秩序，仿佛秩序是人类生存的必然要求。

For him, order does not result from forgetting or ignoring the disorders that plague our existence; order is a necessary development, an improvement that may lead to the Greek ideal of spiritual elevation.

对他来说，秩序并非来自遗忘或无视困扰我们生存的种种混乱；秩序是一种必然的发展，是一种可能通向古希腊精神升华理想的进步。

But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to improve the lot of those to come.

但我们现在已经掌握了足够的知识，能够降低许多曾威胁早期人类生存的风险，并改善后人的命运。
