This blog consists of comments from my real blog, http://scienceblogs.com/stoat/, which I don't want to publish there.
Plus some other stuff convenient to place here.
And its becoming a convenient place for me to dump my comments on other blogs so I can find them again.
Comment: "If Latinos sit out the election instead of saying, "Were going to PUNISH OUR ENEMIES and were gonna reward our friends who stand with us on issues that are important to us," if they don't see that kind of upsurge in voting in this election, then I think its going to be harder, and that's why I think its so important that people focus on voting on November 2." - Barack Hussein Obama [This one is over here, not over there, because it is sourceless and, I suspect, faked. I can find it at thenewamerican but I don't regard that as reliable. If it can be reliably sourced, I'll move it back.]
> When Socrates asked “What is justice?” there was never any doubt that his listeners knew what the word “justice” meant.
This isn't true; different participants to the dialogue have different views. One proposes "might is right" and "Socrates" (really Plato) has no coherent answer to that viewpoint. Interestingly, Justice is indeed very hard to define, unless you accept Hobbes's version, which is to define it as "all that is not unjust", and define *that* as breaking covenants, which I think is an excellent approach (http://scienceblogs.com/stoat/2012/01/30/justice-and-injustice/). This inversion is reminiscent of Popper's.
Meanwhile, the bit about Kepler is over-simplified at best, since motion around the orbit not just its shape was very important.
As to your question, do scientists need to study philosophy of science, I think I'd go for a Kuhn-like paradigm-type answer: 95%+ of scientists are doing factory-science and don't need that kind of stuff; its the 5% who are in some sense thought-leading and truely innovating who need it; but then again, they've already got it, or they wouldn't be there.
