The word " sophist" means a wise and informed person.
Sophist这个字原来指的一个有智慧而且博学的人(按:一般贬称为诡辩学家)。
Almost nothing survives of the voluminous writings of the original or older Sophists, particularly with the first and most famous of them, Protagoras. Three doctrines are associated with Protagoras, although evidence here is scanty and skewed by Plato.
原始智者或较早的智者的大量著作几乎没有留存下来,尤其其中第一位也最著名的智者普罗泰戈 (Protagoras)。三种学说普罗泰戈有关,尽管这里的证据很少而且被柏图歪曲了。
