Science Quotes

From 600+ conversations with the world’s leading thinkers.

The scale of our damage on the animal world is unimaginable. We inflict pain and suffering on wild and domestic animals. We take away their wild lands and habitats, we use them to test our medicines and they're affected by climate change, pollution and many other aspects of our world.

We never have direct access to the world in itself; we only have access to the model our brain is constructing. It works as a sort of 'best guess.' The brain isn't trying to find the absolute truth or create a perfect replica of the outside world's structure.

As far as we know, space goes on for infinity, and yet is expanding at an ever-increasing rate. What is out there? We only understand about 5% of the universe, the rest is made-up of dark energy, dark matter and things we've yet to fully understand. Space triggers that innate curiosity in us about what's out there, where we came from, and the possibilities those answers could bring.

The central premise of my book, the concept of the brain being 'rewired', essentially posits that any change in our behavior results in a change in our brain. This isn't mere conjecture; it's a neurobiological fact. Small behavioral changes trigger small changes in the brain, whereas significant behavioral shifts lead to substantial neural alterations.

So far from being a separate evolutionary lineage with deep roots, we humans were in fact embedded within the great ape family. Humans are now, strictly speaking, firmly ensconced within the chimpanzee family.

Quantum mechanics says our world is nebulous, fuzzy, a haze of possibilities until it somehow snaps to attention upon an appropriate interaction, observation or measurement. That's a very strange reality, and the fact that this theory is so demonstrably correct is radically important to our understanding.

DNA is not life. A single chemical molecule has nothing to do with life. DNA is merely a storage system. Nobody would ever say that the 'Divine Comedy' is the actual paper and ink on which one of its copies is printed, however many influential scientists have supported this nonsensical viewpoint.

I don't see the concept of offsetting as a valid or beneficial solution in the long run. We need to drastically reduce our carbon emissions. If you genuinely delve into the scientific data, it's clear that we are in a significantly dire situation, far more serious than the conventional media discourse would have you believe.

Our ultimate goal is to use this comprehensive analysis to identify the most crucial health improvement strategies for each individual. In essence, we aim to convert complex data into simple, strategic solutions.

The discovery of an effective HIV vaccine is the nirvana for all our efforts to prevent AIDS.

Truth is a quality of reality. It has nothing to do with what I believe. Truth, when it comes to empirical issues, is an objective thing. Whether something is true or not is independent of whether I think it is true or not, and a lot of people confuse this.

Much of the pushback against science is related to a distrust of the establishment and of multinational corporations and their profit motive. It's easy to spread fear; as humans we're very tuned and sensitive to it.
