I wonder what especial sanctity attaches itself to fifteen minutes. It is always the maximum and the minimum of time which will enable us to acquire languages, etiquette, personality, oratory ... One gathers that twelve minutes a day would be hopelessly inadequate, and twenty minutes a wasteful and ridiculous excess.
MONARCH, n. A person engaged in reigning. Formerly the monarch ruled, as the derivation of the word attests, and as many subjects have had occasion to learn.
It is of interest to note that while some dolphins are reported to have learned English - up to fifty words used in correct context - no human being has been reported to have learned dolphinese.
The most important experiences a man can have are those that take him to the very limit; that is the only way we learn, because it requires all our courage.
Ignorance of all things is an evil neither terrible nor excessive, nor yet the greatest of all; but great cleverness and much learning, if they be accompanied by a bad training, are a much greater misfortune.
No matter how much we learn, there is always more knowledge to be gained. In this connection I am reminded of a short poem that has been in my mind over the years. It reads as follow: I used to think I knew I knew. But now I must confess. The more I know I know I know I know I know the less.
