我们三民主义的意思，就是民有、民治、民享。这个民有、民治、民享的意思，就是国家是人民所共有，政治是人民所共管，利益是人民所共享。
《三民主义.民生主义》（1924年8月10日）
The peculiar evil of silencing the expression of an opinion is that it is robbing the human race； posterity as well as the existing generation； those who dissent from the opinion， still more than those who hold it.
Curiosity is the engine of innovation.
The cost of trying is the lowest.
I don't believe in God, but I miss Him.
