Context

“Before Socrates' time, dialectical manners were avoided in good society: they were regarded as bad manners, they were compromising. Young men were cautioned against them. All such proffering of one's reasons was looked upon with suspicion. Honest things like honest men do not carry their reasons on their sleeve in such fashion. It is not good form to make a show of everything. That which needs to be proved cannot be worth much. Wherever authority still belongs to good usage, wherever men do not prove but command, the dialectician is regarded as a sort of clown.” source
