It was her father who struck the keynote to which the tune of her early intellectual life was set. She was about twelve years old at the time, and they were sitting out on the lawn at Fraylingay one day after dinner, as was their wont in the summer--he, on this occasion, under the influence of a good cigar, mellow in mind and moral in sentiment, but inclining to be didactic for the moment because the coffee was late; she in a receptive mood, ready to gather silently, and store with care, in her capacious memory any precept that might fall from his lips, to be taken out and tried as opportunity offered. "Where is your mother?" he asked. "I don't know, father," Evadne answered. "I think she is in the drawing room." "Never say you _think_, my dear, about matters of fact," he said. "When it is possible to _know_ it is your business to find out, and if you cannot find out you must say you don't know. It is moral cowardice, injurious to yourself, not to own your ignorance; and you may also be misleading, or unintentionally deceiving, someone else." "How might the moral cowardice of not owning my ignorance be injurious to myself, father?" she asked. "Why, don't you see," he answered, "you would suffer in two ways? If the habit of inaccuracy became confirmed, your own character would deteriorate; and by leading people to suppose that you are as wise as themselves, you lose opportunities of obtaining useful information. They won't tell you things they think you know already." Evadne bent her brows upon this lesson and reflected; and doubtless it was the origin of the verbal accuracy for which she afterward became notable. Patient investigation had always been a pleasure, but from that time forward it became a principle also. She understood from what her father had said that to know the facts of life exactly is a positive duty; which, in a limited sense, was what he had intended to teach her; but the extent to which she carried the precept would have surprised him.
