I heard sad choirs in my mind. There was nothing left of Rachel in the world. He cherished what he'd shown me, and now it was gone. Eureka.

She didn’t know that loss was alive in the world, a thief always about to slam you and steal everything you had.

I could see why Archimedes got all excited. There was nothing finer than the feeling that came rushing through you when it clicked and you suddenly understood something that had puzzled you. It made you think it just might be possible to get a handle on this old world after all.

The inventors of tools enhance civilization,but the author of ideas enables them to invent.

Marijuana enhances our mind in a way that enables us to take a different perspective from 'high up', to see and evaluate our own lives and the lives of others in a privileged way. Maybe this euphoric and elevating feeling of the ability to step outsidethe box and to look at life’s patterns from this high perspective is the inspiration behind the slang term “high” itself.

Eureka' can be an answer to a question we have never asked. It can be the articulation of a sudden and unforeseen idea or the expression of a magic moment that throws us into a new world. It acts like a radiant sunbeam that comes out of the blue and illuminates a dim past, opening a new, dynamic horizon. It may even be a trivial but lucky encounter with new friends, who let us be what we are in our imagination: original and undifferentiated. (“Waiting for Eureka” ).

We tend to think of imagination and foresight like we are prone to think of life (sometimes) -- as an inscrutable flash of something from the outside that magically takes us over some large boundary in one atomic step. We even call it a flash (of insight), a eureka moment, a light bulb in our heads that suddenly turns on. But if you reflect on this phenomenon for a moment, you know you don't go suddenly from a blank mind to a fully formed solution. You were already thinking about the problem, and other near solutions that don't work, when suddenly you see a new connection that enables you to reuse familiar things on a novel way. Insight comes in small increments, leveraging what was already there.

It is not easy to convey, unless one has experienced it, the dramatic feeling of sudden enlightenment that floods the mind when the right idea finally clicks into place. One immediately sees how many previously puzzling facts are neatly explained by the new hypothesis. One could kick oneself for not having the idea earlier, it now seems so obvious. Yet before, everything was in a fog.
