我很喜欢圣奥古斯丁在“上帝之城”里的一句话,他说“以社会地位评价人是一种罪”。用现在的口吻说,看一个人的名片来决定你是否要和他交谈是罪。对圣奥古斯丁来说,人的价值不在他的社会地位,只有神可以决定一个人的价值,他将在天使围绕、小号奏鸣,天空破开的世界末日给于最后审判,如果你是像我一样的世俗论者,这想法太疯狂了,但这想法有它的价值。
True happiness comes from love for oneself and others.
You have to fight for your dreams, no one is going to hand them to you.
"In the labyrinth of words, we find the keys to our own liberation."
Every tree we plant today is a legacy for future generations.
I don't give a damn if you're offended, I don't care.
