a little strange a few words are necessary to explain its meaning. Some years ago I was listening to an object lesson given to a class of very young children by a pupil teacher who chose for her subject a pot of beautiful fresh green ferns. She began by holding up the plant before the class and asking whether any child could say what it was. At first no child answered, but presently a little girl said, "It is a pot of green feathers." Thereupon the teacher turned to me and said, "Poor little thing! She knows no better."But I fell a thinking on the matter. Did the child really suppose that the ferns were feathers? Or did she rather use the name of a familiar thing to describe what she knew to be different, and yet noticed to be in some respects like?This train of thought led me to put together what I knew of perception, and the following is the result of my labors.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
