Great ambition is the passion of a great character. Those endowed with it may perform very good or very bad acts. All depends on the principals which direct them.
I love readings and my readers, but the din of voices of the audience gives me stage fright, and the din of voices inside whisper that I am a fraud, and that the jig is up. Surely someone will rise up from the audience and say out loud that not only am I not funny and helpful, but I'm annoying, and a phony.
Tradition is but a meteor, which, if it once falls, cannot be rekindled. Memory, once interrupted, is not to be recalled. But written learning is a fixed luminary, which, after the cloud that had hidden it has passed away, is again bright in its proper station. So books are faithful repositories, which may be awhile neglected or forgotten, but when opened again, will again impart instruction.
