The quest for happiness is a universal, scientific, fact. We can measure happiness, we can assess it, and we can devise strategies to make ourselves happy and fulfilled human beings.

Upon experiencing my first miscarriage, I was incredulously told I'd need to endure three consecutive miscarriages before further action would be taken. The idea itself was staggering to me. You wouldn't ask someone to undergo multiple heart attacks or even endure recurrent minor injuries like broken fingers before intervening. Yet, the system requires women to face the trauma of three successive miscarriages. This policy is an absolute miscarriage of justice.

What we perceive to be the absolute truth of the world around us is a complex reconstruction, a virtual reality created by the complex machinations of our minds. We have no idea about the world that we inhabit and what the brain is doing is really creating an entire shortcut that enables us to understand the world without being able to physically really understand the reality in which we inhabit, which is a mind-blowing concept.

Creating digital people is really hard. The quality really matters, especially when it comes to the face. We're so attuned to seeing faces that we pick up anything that doesn't look right. Faces communicate so much- when we see someone else, our imaginations go into overdrive.

If we now want a science of consciousness, we need to find a way of bringing consciousness back into the domain of science. We need to find a way of bringing back together these two domains that Galileo separated. And that is really the challenge as I see it.
