His mind was not in a normal state. A healthy man usually thinks of, feels, and remembers innumerable things simultaneously, but has the power and will to select one sequence of thoughts or events on which to fix his whole attention. A healthy man can tear himself away from the deepest reflections to say a civil word to someone who comes in and can then return again to his own thoughts. But Prince Andréy’s mind was not in a normal state in that respect. All the powers of his mind were more active and clearer than ever, but they acted apart from his will. Most diverse thoughts and images occupied him simultaneously. At times his brain suddenly began to work with a vigor, clearness, and depth it had never reached when he was in health, but suddenly in the midst of its work it would turn to some unexpected idea and he had not the strength to turn it back again.
