At least 15 percent of human females possess a genetic mutation that gives them an extra (fourth) type of color photoreceptor - and this allows them to discriminate between colors that look identical to the majority of us with a mere three types of color photoreceptors.

Keep in mind that every single generation before us has worked under the assumption that they possessed all the major tools for understanding the universe, and they were all wrong, without exception.

Brains are like representative democracies. They are built of multiple, overlapping experts who weigh in and compete over different choices.

You are part of a complex social network that changes your biology with every interaction, and which your actions can change.

We open our eyes and we think we're seeing the whole world out there. But what has become clear—and really just in the last few centuries—is that when you look at the electro-magnetic spectrum we are seeing less than 1/10 Billionth of the information that's riding on there. So we call that visible light. But everything else passing through our bodies is completely invisible to us. Even though we accept the reality that's presented to us, we're really only seeing a little window of what's happening.
