Schopenhauer’s advice to the young philosopher

Hi all, 
I remember reading something titled as above, but I cannot find it anywhere. If anyone knows about it and is willing to provide me with sources, I would appreciate it very much. Thanks in advance!

>No child under the age of fifteen should receive instruction in subjects which may possibly be the vehicle of serious error, such as philosophy, religion, or any other branch of knowledge where it is necessary to take large views; because wrong notions imbibed early can seldom be rooted out, and of all the intellectual faculties, judgment is the last to arrive at maturity. The child should give its attention either to subjects where no error is possible at all, such as mathematics, or to those in which there is no particular danger in making a mistake, such as languages, natural science, history and so on.
