It has more enemies than appear at first sight.

Inertness of mind, the desire to do things cheaply, dislike of mental effort, the tendency to be satisfied with appearances, the wish to shine, impatience for results, all foster intellectual insincerity; just as, in conduct, the wish to please, the spirit of accommodation and expediency, the fear of blame, the instinct of concealment, which is inborn in many girls, destroy frankness of character and make people untrue who would not willingly be untruthful.

Yet even truthfulness is not such a matter of course as many would be willing to assume.

To be inaccurate through thoughtless laziness in the use of words is extremely common, to exaggerate according to the mood of the moment, to say more than one means and cover one's retreat with "I didn't mean it," to pull facts into shape to suit particular ends, are demoralizing forms of untruthfulness, common, but often unrecognized.
If a teacher could only excel in one high quality for training girls, probably the best in which she could excel would be a great sincerity, which would train them in frankness, and in the knowledge that to be entirely frank means to lay down a great price for that costly attainment, a perfectly honourable and fearless life.
