It's awful undermining to the intellect, German is; you want to take it in small doses, or first you know your brains all run together, and you feel them flapping around in your head same as so much drawn butter.
My philological studies have satisfied me that a gifted person ought to learn English (barring spelling and pronouncing) in thirty hours, French in thirty days, and German in thirty years. It seems manifest, then, that the latter tongue ought to be trimmed down and repaired. If it is to remain as it is, it ought to be gently and reverently set aside among the dead languages, for only the dead have time to learn it.
