《菜根谭·概论》
人的一生有苦有乐，只有从苦难中磨练出来的幸福才能长久；在求学中，抱着既怀疑又相信的态度去勘验实证，这样得到的学问才是真学问。
一苦一乐相磨练，练极而成福者，其福始久﹕一疑一信相参勘，勘极而成知者，其知始真。
One's life involves bitterness and happiness. Only by tempering yourself through hardship can you have lasting happiness. When you pursue knowledge, you should take an attitude of suspicion and belief to prove and verify it; only then can you gain true knowledge.
