After I had finished my studies at the High School and matriculated at the medical schools of the Leipsic University, my father sent for me to come during my vacation to Rome, where he still lived, and a few weeks before my twenty-fifth birthday I rode through the Porta del Popolo. The evening before that anniversary my father took out the phial, showed it to me, and asked me what I thought of the verses that he had written on a label and attached to the bottle. I read them, and they ran as follows: In hearts alone where modesty resides Is found the priceless treasure of Pure Truth. If pride within you secretly abides That, forced by the elixir's charm, The Sooth You needs must speak--be wholly pure in thought, Despising not the teachings wise, of old; When Truth with equal earnestness was sought If speech be silver, silence then is gold! The scales seemed to fall from my eyes, and I realised why the Ueberhells had borne such an evil and dreaded name among their fellow-citizens. The day after I, too, was to use the elixir and I asked my father: "What shall I do if the power of the essence forces me to speak out everything that is true, simply because it is true, even when it is against my wish and will tend to my own annoyance and distress, as well as to that of others?" And he replied solemnly: "The truth? Has any one yet found the right answer to the old question: 'What is Truth?' Can you be sure that the noble and mighty Goddess corresponds to your puny and individual conception of her?" This very idea had disturbed me during my ride over the Alps, and I exclaimed: "Therein lies the dangerous power of the elixir! It kindles in our minds the confidence that we know the truth by means of a charm, whereas we can only possess the desire to seek for it. Our certainty also misleads us to constrain others to think as we think, and to despise them and persecute them when they differ from us. The elixir made you happy, my father, because you are good and pure, and because the beautiful, to the pursuit of which you have dedicated your life, ennobles everyone and makes every thing harmonious that comes from you. "But many generations had to pass before you appeared to do honour to the powers of the elixir. I myself have been cast in a less heroic mould, and who can prophesy what my children, if I ever have any, will be like. In this world where every thing is deceitful, and no one is outspoken, the man who alone is under the necessity of proclaiming what he considers the truth, is like a warrior who opposes himself without shield or harness to a fully armed foe. Therefore, my dear father, I am very reluctant to make use of the elixir to-morrow."
