But the medical profession should be left still more to their own discretion than other artists, in proportion to the greater nobility of their aims and usefulness of their work; this art should have a special right of choosing its objects; this sacred occupation, taught straight from Heaven, and pursued by the wisest of men, should be secured against all compulsion, enslaved to no law, intimidated and penalized by no court, exposed to no votes or paternal threats or uninstructed passions. If I had told my father directly and expressly, 'I will not do it, I refuse the case, though I could treat it, I hold my art at no man's service but my own and yours, as far as others are concerned I am a layman'--if I had taken that position, where is the masterful despot who would have applied force and compelled me to practise against my will? The appropriate inducements are request and entreaty, not laws and browbeating and tribunals; the physician is to be persuaded, not commanded; he is to choose, not be terrorized; he is not to be haled to his patient, but to come with his consent and at his pleasure. Governments are wont to give physicians the public recognition of honours, precedence, immunities and privileges; and shall the art which has State immunities not be exempt from the _patria fotestas_? All this I was entitled to say simply as a professional man, even on the assumption that you had had me taught, and devoted much care and expense to my training, that this particular case had been within my competence, and I had yet declined it. But in fact you have to consider also how utterly unreasonable it is that you should not let me use at my own discretion my own acquisition. It was not as your son nor under your authority that I acquired this art; and yet it was for your advantage that I acquired it--you were the first to profit by it--, though you had contributed nothing to my training. Will you mention the fees you paid? How much did the stock of my surgery cost you? Not one penny. I was a pauper, I knew not where to turn for necessaries, and I owed my instruction to my teachers' charity. The provision my father made for my education was sorrow, desolation, distress, estrangement from my friends and banishment from my family. And do you then claim to have the use of my skill, the absolute control of what was acquired independently? You should be content with the previous service rendered to yourself, not under obligation, but of free will; for even on that occasion nothing could have been demanded of me on the score of gratitude.
