What is wanted is the means of making ignorance aware of itself, and able to profit by knowledge

Context

“But the objection shows a very imperfect understanding of the function of popular institutions as a means of political instruction. It is but a poor education that associates ignorance with ignorance, and leaves them, if they care for knowledge, to grope their way to it without help, and to do without it if they do not. What is wanted is the means of making ignorance aware of itself, and able to profit by knowledge; accustoming minds which know only routine to act upon, and feel the value of principles; teaching them to compare different modes of action, and learn, by the use of their reason, to distinguish the best.” source
