Well then, having, as you see, completely foisted the ultimate issue upon your own shoulders, it seems to me that there are three main standpoints from which you must regard our profession before finally deciding to embark upon it. To take the least important of these first, you must bear in mind, I think, that while you should undoubtedly be able to pay your way, and to make an honest living, yet the financial rewards that medicine has to offer are scarcely worth considering. Given an equal amount of capital, both in brain-power and pounds sterling, your hours of work, your expenditure of energy, your capacity for diagnosis and research, your readiness at the reading of human nature, would bring you a far greater return of this world's goods in almost any other occupation that you care to name--incomparably so in commerce. At the same time I don't think that this point of view will detain you very long; because, however little fathers may really know of their own sons (and the sum of parental ignorance under this heading must be something rather stupendous), I am quite sure that the financial laurel, _per se_, has no overwhelming attraction for you. Having deigned then to consider the problem from this lowest and most sordid standpoint, you should shift your ground, I think, and reflect upon it from the midmost of my three Pisgahs, the scientific one. If I haven't led you to this first, it is because you have probably scrambled up it already, and paid no attention at all to the one that I have just recommended to you. And in a sense your instinct will perhaps have taken you by a straighter route to the heart of this matter than that which your more prudent parent has indicated. Because ultimately it is from this point that you will have to make your final decision. You must ask yourself, with all the earnestness of a novice at his altar-vigil, "Am I prepared to _know_?" For the long day of the charlatan and the quack is drawing at last to its close, and their sun is even now setting in a blaze of patent-medicine advertisements. Modern Europe has almost ceased to be possible for the would-be Paracelsus; even America will not contain him, I think, for very much longer. And through a dissolving mist of white spats and atrocious Latin the eyes of humanity are turning slowly, but very surely, towards the man who _knows_. Are you prepared to become such a man?
