Froebel and Education Through Self-Activity #233269

When through a long period of time one has been a constant student of some particular subject, it becomes extremely dificult to attribute to their right sources all the ideas concerning it in possession of which one happens to find oneself, — and quite out of the ques tion if the possible sources are numerous. Besides, in common politeness to oneself one must consider some of the ideas home-grown, even though they resemble ideas to be found elsewhere. I have, however, done my best to acknowledge all conscious borrowings; and if it is to be my unhappy fate to have others brought to my consciousness later on, I apologize beforehand, and will make due reparation in other editions.
