Interlocutor Quotes

Socrates splits himself into two, so that there are two Socrates: the Socrates who knows in advance how the discussion is going to end, and the Socrates who travels the entire dialectical path along with his interlocutor. (Pierre Hadot)
There was a Socratic style of life (which the Cynics were to imitate), and the Socratic dialogue was an exercise which brought Socrates' interlocutor to put himself in question, to take care of himself, and to make his soul as beautiful and wise as possible.
Pierre Hadot
In Plato's Republic, when the interlocutor of Socrates appears to bring certain plausible reasons to bear upon the mathematical sciences, to show that they are useful to human life, arithmetic for reckoning, distributions, contributions, exchanges, and partnerships, geometry for sieges, the founding of cities and sanctuaries, and the partition of land, music for festivals, entertainment, and the worship of the gods, and the doctrine of the spheres, or astronomy, for farming, navigation and other undertakings, revealing beforehand the proper procedure and suitable season, Socrates, reproaching him says: "You amuse me, because you seem to fear that these are useless studies that I recommend; but that is very difficult, nay, impossible. For the eye of the soul, blinded and buried by other pursuits, is rekindled and aroused again by these and these alone, and it is better that this be saved than thousands of bodily eyes, for by it alone is the truth of the universe beheld."
Nicomachus
As to the mouth, it delights at times in laughter; it is disposed to impart all that the brain conceives; though I daresay it would be silent on much the heart experiences. Mobile and flexible, it was never intended to be compressed in the eternal silence of solitude: it is a mouth which should speak much and smile often, and have human affection for its interlocutor.

Nixon was one of the most gifted of American Presidents, prepared to make tough decisions and courageous in doing so. But he needed solitude for such an act. Face-to-face, Nixon was obsessively incapable of overruling an interlocutor or even disagreeing with him.

When in the sciences or techniques one states that a certain problem is unsolvable, a rigorous demonstration of such unsolvability is required. And when a scientist submits an article to publication, the least that its referees demand is that it be intelligible. Why? Because rational beings long for understanding and because only clear statements are susceptible to be put to examination to verify whether they are true or false. In the Humanities it is the same, or it should be, but it is not always so. Nietzsche reproached John Stuart Mill's clarity. Henri Bergson, although an intuitionist himself, wrote clearly and declared that "clarity is the philosopher's courtesy". Obscurity is rude, because it assumes the interlocutor is incapable of understanding and dialoguing.
