In my experience, many skilled philosophers who work in the Anglo-American tradition will tend to have a feverish streak. They will tend to find a research program which conforms with their intuitions (some of which may be treated as “foundational” or givens), and then hold onto that program for dear life. This kind of philosopher will change her mind only on rare occasions, and even then only on minor quibbles that do not threaten her central programme. We might call this kind of philosopher a “programmist” or “anti-skeptic“, since the programmist downplays the importance of humility, and is more interested in characterizing herself in terms of the other virtues like philosophical rigour.
You could name a great many philosophers who seem to hold this character. Patricia and Paul Churchland come to mind: both have long held the view that the progress of neuroscience will require the radical reformation of our folk psychological vocabulary. However, when I try to think of a modern exemplar of this tradition, I tend to think of W.V.O. Quine, who held fast to most of his doctrinal commitments throughout his lifetime: his epistemological naturalism and holism, to take two examples. This is just to say that Quine thought that the interesting metaphysical questions were answerable by science. Refutation of the deeper forms of skepticism was not very high on Quine’s agenda; if there is a Cartesian demon, he waits in vain for the naturalist’s attention. The most attractive spin on the programmist’s way of doing things is by saying they have raised philosophy to the level of a craft, if not a science.

“What’s attractive about looking at all philosophers in part suspiciously and in part mockingly is not that we find again and again how innocent they are… but that they are not honest enough in what they do, while, as a group, they make huge, virtuous noises as soon as the problem of truthfulness is touched on, even remotely.” – Nietzsche, Beyond Good & Evil
Programmists are common among philosophers today. But if I were to take you into a time machine and introduced you to the elder philosophers, then it would be easy to lose all sense of how the moderns compare with their predecessors. The first philosophers lived in a world where science was young, if not absent altogether; there was no end of mystery to how the universe got on. For many of them, there was no denying that skepticism deserved a place at the table. From what we can tell from what they left behind, many ancient philosophers (save Aristotle and Pythagoras) did not possess the quality that we now think of as analytic rigour. The focus was, instead, of developing the right kind of life, and then — well, living it.
