When I was seven or eight years old, I began to read the science-fiction magazines that were brought by guests into my grandparents‘ boarding house in Waukegan, Illinois.

I have fallen in love with the imagination. And if you fall in love with the imagination, you understand that it is a free spirit. It will go anywhere, and it can do anything.

Regarding life, the wisest men of all ages have judged alike: it is worthless.

Life would be infinitely happier if we could only be born at the age of eighty and gradually approach eighteen.

Wisdom has its root in goodness, not goodness its root in wisdom.

Never go to excess, but let moderation be your guide.

Imagination is the beginning of creation. You imagine what you desire, you will what you imagine and at last you create what you will.

Education is hanging around until you’ve caught on.

Progressive art can assist people to learn not only about the objective forces at work in the society in which they live, but also about the intensely social character of their interior lives. Ultimately, it can propel people toward social emancipation.

From things that have happened and from things as they exist and from all things that you know and all those you cannot know, you make something through your invention that is not a representation but a whole new thing truer than anything true and alive, and you make it alive, and if you make it well enough, you give it immortality.

One who does not know when to die, does not know how to live.
