The word " sophist" means a wise and informed person.
Sophist这个字原来指的是一个有智慧而且博学的人(按:一般贬称为诡学家)。
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,尤其是其中第一位也是最著名的智者普罗泰戈拉 (Protagoras)。三种学说与普罗泰戈拉有关,尽管这里的证据很少而且被柏拉图歪曲了。
