family, and trained by the same individual, still are different as to the degree of their comprehension and intelligence. One will make rapid progress, one will receive instruction only gradually, one will remain at the lowest stage of all. For no matter how much you may polish a shell, it will not turn into a gleaming pearl, nor can you change a dull pebble into a gem whose pure rays will light the world. Never, through training and cultivation, will the colocynth and the bitter tree1 change into the Tree of Blessedness.2 That is to say, education cannot alter the inner essence of a man, but it doth exert tremendous influence, and with this power it can bring forth from the individual whatever perfections and capacities are deposited within him. A grain of wheat, when cultivated by the farmer, will yield a whole harvest, and a seed, through the gardener’s care, will grow into a great tree. Thanks to a teacher’s loving efforts, the children of the primary school may reach the highest levels of achievement; indeed, his benefactions may lift some child of small account to an exalted throne. Thus is it clearly demonstrated that by their essential nature, minds vary as to their capacity, while education also playeth a great role and exerteth a powerful effect on their development.
