In advising the constitutional worrier the chief trouble the physician finds is an active opposition on the part of the patient. Instead of accepting another's estimate of his condition, and another's suggestions for its relief, he comes with a preconceived notion of his own difficulties, and with an insistent demand for their instant relief by drug or otherwise. He uses up his mental energy, and loses his temper, in the effort to convince his physician that he is _not_ argumentative. In a less unreasonable, but equally difficult class, come those who recognize the likeness in the portrait painted by the consultant, but who say they have tried everything he suggests, but simply "can't." It is my hope that some of the argumentative class may recognize, in my description, their own case instead of their neighbor's, and may of their own initiative adopt some of the suggestions; moreover, that some of the acquiescent, but despairing class will renew their efforts in a different spirit. The aim is, not to accomplish a complete and sudden cure, but to gain something every day, or if losing a little to-day, to gain a little to-morrow, and ultimately to find one's self on a somewhat higher plane, without discouragement though not completely freed from the trammels entailed by faulty mental habit. II. EPICURUS AS A MENTAL HEALER 'Tis to believe what men inspired of old, Faithful, and faithfully informed, unfold. _Cowper_. The suggestions offered in the following pages are not new. Many of them were voiced by Epicurus three hundred years before Christ, and even then were ancient history. Unfortunately Epicurus had his detractors. One, Timocrates, in particular, a renegade from his school, spread malicious and unfounded reports of his doings and sayings, reports too easily credited then, and starting, perhaps, the misconception which to-day prevails regarding the aims of this philosopher. But when Marcus Aurelius, nearly five centuries later, decided to endow a philosophical professoriate he established the Epicurean as one of the four standard schools. The endorsement of such a one should surely predispose us to believe the authentic commentators of Epicurus, and to discredit the popular notion which makes his cult synonymous with the gratification of the appetites, instead of with the mental tranquility to which he regarded sensual pleasures so detrimental that he practically limited his diet, and that of his disciples, to bread and water.
