“Pride is yet again in the way of our mind’s ability to accept that we may not be the most intelligent and advanced people in the universe or on Earth since it was formed along with the solar system 4.5 billion years ago.”

“While the Copernican principle comes with no guarantees that it will forever guide us to cosmic truths, it's worked quite well so far: not only is Earth not in the center of the solar system, but the solar system is not in the center of the Milky Way galaxy, the Milky Way galaxy is not in the center of the universe, and it may come to pass that our universe is just one of many that comprise a multiverse. And in case you're one of those people who thinks that the edge may be a special place, we are not at the edge of anything either.”

“The suppression of uncomfortable ideas may be common in religion or in politics, but it is not the path to knowledge, and there's no place for it in the endeavor of science. We do not know beforehand where fundamental insights will arise from about our mysterious and lovely solar system. The history of our study of our solar system shows us clearly that accepted and conventional ideas are often wrong, and that fundamental insights can arise from the most unexpected sources.”

“The ability to expend energy, especially in the form of other people's labour, in non-utilitarian ways, is the most basic and universally understood symbol of power.”

“The atoms of our bodies are traceable to stars that manufactured them in their cores and exploded these enriched ingredients across our galaxy, billions of years ago. For this reason, we are biologically connected to every other living thing in the world. We are chemically connected to all molecules on Earth. And we are atomically connected to all atoms in the universe. We are not figuratively, but literally stardust.”

“Look, here is a tree in the garden and every summer is produces apples, and we call it an apple tree because the tree "apples." That's what it does. Alright, now here is a solar system inside a galaxy, and one of the peculiarities of this solar system is that at least on the planet earth, the thing peoples! In just the same way that an apple tree apples!”
