而是
Words and deeds are not separate， but intimately connected.
A 'performative' utterance is not true or false， but happy or unhappy.
Words are not mere sounds or marks， but signs of facts.
The question is not， Can they reason？ nor， Can they talk？ but， Can they suffer？
The ultimate tragedy is not the oppression and cruelty by the bad people but the silence over that by the good people.
In the end， we will remember not the words of our enemies， but the silence of our friends.
The ultimate measure of a man is not where he stands in moments of comfort and convenience， but where he stands at times of challenge and controversy.
Judge a man by his questions rather than by his answers.
