Stephen Jay Gould

The universe is not a clockwork mechanism. It is a dynamic, evolving system.

Evolution is not a theory about the origin of life. It is a theory about the diversification of life.

The history of life is full of surprises. It is not a straight line from simple to complex.

Science is a human activity, and like all human activities, it is subject to error.

The most important thing to teach students is not what to think, but how to think.

The universe is not designed for us. We are just a small part of a much larger story.

Science is a conversation, not a monologue.

The history of life is a story of constant change and adaptation.

The greatest strength of science is its ability to admit when it is wrong.

Evolution is not a belief system. It is a scientific explanation for the diversity of life.

The history of life is a story of trial and error, not perfect design.

Science is a journey, not a destination.

The most important thing to remember about the human brain is that it is a product of evolution.

The universe is a vast and mysterious place, and we are only just beginning to understand it.

Science is a tool for understanding the world, not for dictating how we should live our lives.

Evolution is not a theory about how humans came to be. It is a theory about how all life came to be.

Science is a collaborative effort. It is built on the work of many individuals.

The most important thing to remember about human nature is that it is complex and multifaceted.

The universe is full of wonders, and science is the key to unlocking them.

Science is a powerful tool, but it is not the only way of knowing.
