Lack of Agreement Among Philosophers

I'm reading Marvin Farber's (1901-1980) book "Basic Issues of Philosophy: Experience, Reality, and Human Values" (Harper Torchbooks, 1968). In his opening chapter he writes:

"The lack of general agreement among philosophers, whether in different historical periods or at a given time, has been the cause of much criticism. Many of the differences in philosophical views may be attributed to the diversity of motives which lead thinkers to more ultimate speculation or inquiry."

You could replace the word philosophers with almost any branch of study and the statement would make as much sense. People often criticize various disciplines for their abundance of disunity and disagreement and point to this as evidence of the weakness of the discipline. On the contrary it is out of the multitude of views that critical debate arises and progress is made. I believe that this was Paul Feyerabend's point in recognizing and encouraging anarchism in the scientific disciplines. Science (and other disciplines) are weakened when there is too much pressure for conformity to particular theories and viewpoints. Only in a perfect world would perfect conformity be an asset. The key to making the most of our disagreements is to enter into and continue the dialogue.
