Albert Einstein did express his thoughts on humanity and various aspects of human existence throughout his life. Here are a few notable quotes that reflect his views:
"A human being is a part of the whole called by us 'universe,' a part limited in time and space. He experiences himself, his thoughts and feelings, as something separate from the rest—a kind of optical delusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty." (From a letter to Erik Gutkind, 1954)
"I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution." (From an interview with G. S. Viereck, 1929)
"The most beautiful thing we can experience is the mysterious. It is the source of all true art and science." (From The World As I See It, 1931)
"I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world." (From Cosmic Religion: With Other Opinions and Aphorisms, 1931)
It is important to note that Einstein's views on humanity encompassed a wide range of topics beyond science, including ethics, peace, education, and the interconnectedness of all living beings.
