Health is the soul that animates all the enjoyments of life, which fade and are tasteless without it.

I decided to sell my drawings. However, I didn't want people to buy my drawings because the professor of physics isn't supposed to be able to draw - isn't that wonderful - so I made up a false name.

Many are they who have a taste and love for drawing, but no talent; and this will be discernible in boys who are not diligent and never finish their drawings with shading.

No better way is there to learn to love Nature than to understand Art. It dignifies every flower of the field. And, the boy who sees the thing of beauty which a bird on the wing becomes when transferred to wood or canvas will probably not throw the customary stone.

I am an optimist. It does not seem too much use being anything else.
