A quality which singularly contrasts with woman's vague idealism is the accuracy she displays in business. This is due to her being fundamentally inaccurate. It is not the accurate people who are always accurate; it is the inaccurate people on their guard.[3] Woman's interest in the particular predisposes her to the exact, for accuracy may be defined as a continuous interest in the particular. I suspect that it indicates a probability that by education, and especially encouragement, woman may develop a far higher degree of concentration than she has hitherto done. In her way stands a fatal facility, that of grasping ideas before they are half-expressed. It is a quality of imagination, natural rather than induced. Any schoolteacher will confirm the statement that in a mixed class, aged eleven to twelve, the essays of the girls are better than those of the boys. This is not so in a mixed university. I suspect that this latter is quite as much due to the academic judgment, which does not recognize imagination, as to the fact that in the later years of their lives the energies of girls are diverted from intellectual concentration (and also expression) toward the artistic and the social. This untrained concentration produces a certain superficiality and an impetuousness which harmonize with the intrusion of side issues,--to which I have referred,--and with the burgeoning of side issues on the general idea. [3] I have observed for two years the steady growth in the accuracy of the work of Case 33, due to her having concentrated upon her instinctive inaccuracy.--THE AUTHOR. Nowhere is this better shown than in the postscript habit. Men do not, as a rule, use postscripts, and it is significant that artists and persons inclined toward the arts are much more given to postscripts than other kinds of men. One might almost say that women correspond by postscript; some of them put the subject of the letter in the postscript, as the scorpion keeps his poison in his tail. I have before me letters from Case 58, with two postscripts, and one extraordinary letter from Case 11, with four postscripts and a sentence written outside the envelope. This is the apogee of superficiality. The writers have run on, seduced by irrelevance, and have not been able to stop to consider in all its bearings the subject of the letter. Each postscript represents a development or qualification, which must indicate the waste by bad education of what may be a very good mind.
