I love thinking about and discussing philosophy; I consider it an extremely important discipline.
But: In mathematics, many results have been discovered that are virtually certain to be true, especially over the past 300 years or so. There now exists a veritable mountain of results, with later results built upon earlier ones.
Excluding that part of philosophy that may be said to overlap with mathematics (like symbolic logic and set theory), are there any results in philosophy that have been generally accepted by philosophers as either certain or nearly certain?
Or on the other hand, are there not really any such results in philosophy? Is philosophy nothing more than an endless series of discussions, devoid of widely accepted conclusions?
