Neurath's boat

Neurath's boat goes by other names, for example, Neurathian Bootstrap. 

The wiki entry includes this passage from Willard Van Orman Quine, who writes in Word and Object:

"We are like sailors who on the open sea must reconstruct their ship but are never able to start afresh from the bottom. Where a beam is taken away a new one must at once be put there, and for this the rest of the ship is used as support. In this way, by using the old beams and driftwood the ship can be shaped entirely anew, but only by gradual reconstruction."

Anyway, have a great weekend everyone!

Neurath's boat

There are many references to Neurath's boat in various places on the web, and one nice paper that relates to ethics is by Gilbert Harman of Princeton University. "Three Trends in Moral and Political Philosophy" is available as a pdf file and may be of interest to some of you.
