In 1815 Dr. Samuel Hahnemann wrote on homeopathy:

"Our art requires no political lever, no worldly decorations in order to become something.  It grows gradually, at first unrecognized, surrounded as it were by all manner of weeds which luxuriate around it, from an insignificant acorn to a sapling, soon its summit will overtop the rank weeds.  Patience! It is striking deep its roots into the earth, it is increasing in strength imperceptibly but all the more surely and will in its own time grow into an oak of God, which no longer is shaken by storms, spreads out its branches into all regions that suffering mankind may be healed under its beneficent shade."
