Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution.

Somewhere, something incredible is waiting to be known.

Knowledge will give you power, but character, respect.

As our circle of knowledge expands, so does the circumference of darkness surrounding it.

I'm not a master, I'm a student-master, meaning that I have the knowledge of a master and the expertise of a master, but I'm still learning, So I'm a student-master. I don't believe in the word master, I consider the master as such when they close the casket.

If I give you a pfennig, you will be one pfennig richer and I'll be one pfennig poorer. But if I give you an idea, you will have a new idea, but I shall still have it, too.

The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead, and his eyes are dimmed. It was the experience of mystery — even if mixed with fear — that engendered religion. A knowledge of the existence of something we cannot penetrate, our perceptions of the profoundest reason and the most radiant beauty, which only in their most primitive forms are accessible to our minds: it is this knowledge and this emotion that constitute true religiosity. In this sense, and only this sense, I am a deeply religious man.

The further the spiritual evolution of mankind advances, the more certain it seems to me that the path to genuine religiosity does not lie through the fear of life, and the fear of death, and blind faith, but through striving after rational knowledge.

If knowledge can create problems, it is not through ignorance that we can solve them.

For in much wisdom is much grief; and he that increaseth knowledge increaseth sorrow.
