"Anyone who acquires more than the usual amount of knowledge concerning a subject is bound to leave it as his contribution to the knowledge of the world"

This quote by Liberty Hyde Bailey speaks to the significance of understanding and the impact it can have on the world. It suggests that when somebody acquires a greater than average amount of understanding on a specific subject, they need to utilize it to contribute to the cumulative understanding of the world. This could be done through teaching, composing, or other types of interaction. By sharing their knowledge, they can help to broaden the understanding of the subject and make it more accessible to others. This quote encourages individuals to use their understanding to benefit the world, instead of keeping it to themselves. It is a suggestion that knowledge is a powerful tool and should be used to benefit society.
