Instead it has a duty to its citizens to maintain the freedom, to let those citizens contribute to the further adventure and the development of the human race.” ~ Richard P. Feynman

not repeated assessment of their validity.” ~ Edward de Bono
- “Awareness is the key. Do we see the stories that we’re telling ourselves and question their validity? When we are distracted by strong emotion, do we remember that it is our path? Can we feel the emotion and breathe it into our hearts for ourselves and everyone else? If we can remember to experiment like this even occasionally, we are training as a warrior. And when we can’t practice when distracted but KNOW we can’t, we are still training well. Never underestimate the power of compassionately recognizing what’s going on.” ~ Pema Chodron
- “The treatment of the indeterminacy principle as absolute and final can then be criticized as constituting an arbitrary restriction on scientific theories, since it does not follow from the quantum theory as such, but rather from the assumption of the unlimited validity of certain of its features, an assumption that can in no way ever be subjected to experimental proof.” ~ David Bohm

- “Absurdism, like methodical doubt, has wiped the slate clean. It leaves us in a blind alley. But, like methodical doubt, it can, by returning upon itself, open up a new field of investigation, and in the process of reasoning then pursues the same course. I proclaim that I believe in nothing and that everything is absurd, but I cannot doubt the validity of my proclamation and I must at least believe in my protest.” ~ Albert Camus
