but talking is part of the contest (I should not have said it was about "text"; nonetheless academia still maintains an oral tradition in teaching and thesis defenses)

so while written philosophy is verbose, philosophers talking can "transfer" a lot of "meaning" with short sentence

whereas mathematicians will likely need to talk for a very long time for what they can write down in a short terse equation

Who do the few words trick? Why do the philosophers wait for that before writing their many words?
