Guy P. Harrison Quotes

It's never too late to think.

On the potential discoveries of the James Webb Space Telescope: “Collectively, as a species, we are standing at the mouth of the deepest and darkest cave of all. As we lean in and turn on the flashlight, we can be confident that wonderful secrets await.”

Don't worry about winning debates and beating up people in heated arguments. That stuff is rarely enjoyable or productive. Instead offer a helping hand. Be positive. Teach. Try to inspire people to think better for their own good.

QAnon is a claim so extraordinarily vacuous that it can almost serve as the perfect litmus test for the pathological absence of critical thinking.

Racism is an avoidable culture clash masquerading as inescapable biological warfare.

All known life on Earth today is fundamentally similar, is genetically related, and shares descent from a single-celled common ancestor that lived at least 3 or 4 billion years ago. . . . Sometimes I get so wrapped up in thoughts about evolution, biodiversity, and the surprisingly close relationships between lifeforms that I look around and see only slight variations of genetic code.

“It’s scary to think about, but we may finally find unity as a species in self-destruction. The first minute of World War III will render nations, races, and religions meaningless concepts because the first thing to die in nuclear fire will be all our beloved imaginary borders."

But even bad museums can have value. The Creation Museum (Kentucky, USA), for example, may be a vulgar monument to pseudoscience and deception, but it can teach us important things about American culture and humankind in general. I visited museums in a couple of communist countries that were like supervolcanoes of absurd propaganda. But they made me think more about patriotism and the national mythologies of all countries.

The basic understanding of evolution that I carry around in my head enhances my life. I've done night dives in the Caribbean, 130 feet down, and there were moments when I might have felt like an astronaut visiting some alien planet filled with exotic life. But I knew better. I was home and all the weird and wonderful lifeforms around me were family. The magnificence and importance of nature are clarified and amplified in light of the awareness of shared ancestors and a common origin. I understand that I'm inside the big beautiful blur of life that surrounds our world. And that makes the ride even more amazing.

“We do not see the world. We watch internal movies about the world."

Critical thinking is the indispensable skill for smart living in modern society, and skepticism is the essential posture for the fully awake twenty-first-century human being.

“This is an exciting moment in human history. Collectively, as a species, we are standing at the mouth of the deepest and darkest cave of all. As we lean in and turn on the flashlight, we can be confident that wonderful secrets await.

Evolution is the long blur, a constant and living flow of branching relationships. One thing is always connected to another and another. Having no regard for our love of labels and organization, life rolls on as a continual stream of organic matter. The important thing about the origin of the human brain is not pinpointing some specific time, event, or fossil to declare a beginning in order to satisfy our desire for order. What matters is that we understand the process from which it emerged and how deeply rooted the modern human brain is to its past.

Humility is the key. If you are an arrogant, condescending skeptic then you are doing it wrong. Science and critical thinking rest upon a premise that says anyone can be wrong about anything. A good thinker is humble. We also must be mindful of the fact that very intelligent people can hold very dumb beliefs. It's a human condition. Irrational believers are not inferior people; they simply made a misstep somewhere along the way in their thinking.

It's the 21st century and still we have no universally agreed upon definition of life. It seems the universe does not care about our desire for tidy categories and tight descriptions. Our intellectual comfort is irrelevant to reality. When it comes to life, gray zones and blurry boundaries abound. This is bizarre considering life has been on our planet for more than 3.5 billion years and it's all around us now. Life saturates Earth's surface zone, from more than a mile deep in the crust to the stratosphere miles above. Its diversity and overall success are staggering, difficult to comprehend. For example, some scientists estimate that there are more than one trillion species alive right now. In total, Earth may have hosted more than 100 trillion species so far. Life is no stranger to us. And yet, what is it?
