Roughly speaking, there are three kinds of people in this world. The first kind of people are People; they are the largest and probably the most valuable class. We owe to this class the chairs we sit down on, the clothes we wear, the houses we live in; and, indeed (when we come to think of it), we probably belong to this class ourselves. The second class may be called for convenience the Poets; they are often a nuisance to their families, but, generally speaking, a blessing to mankind. The third class is that of the Professors or Intellectuals; sometimes described as the thoughtful people; and these are a blight and a desolation both to their families and also to mankind. Of course, the classification sometimes overlaps, like all classification. Some good people are almost poets and some bad poets are almost professors. But the division follows lines of real psychological cleavage. I do not offer it lightly. It has been the fruit of more than eighteen minutes of earnest reflection and research.
[G. K. Chesterton, "The Three Kinds of Men", in Alarms and Discursions.]
