You Could Just As Well Say That

If We Could Travel Into The Past, It's Mind-boggling What Would Be Possible. For One Thing, History Would Become An Experimental Science, Which It Certainly Isn't Today. The Possible Insights Into Our Own Past And Nature And Origins Would Be Dazzling. For Another, We Would Be Facing The Deep Paradoxes Of Interfering With The Scheme Of Causality That Has Led To Our Own Time And Ourselves. I Have No Idea Whether It's Possible, But It's Certainly Worth Exploring.

The Impediment To Scientific Thinking Is Not, I Think, The Difficulty Of The Subject. Complex Intellectual Feats Have Been Mainstays Even Of Oppressed Cultures. Shamans, Magicians And Theologians Are Highly Skilled In Their Intricate And Arcane Arts. No, The Impediment Is Political And Hierarchical.

We Are The Children Equally Of The Sky And The Earth.

Every One Of Us Is, In The Cosmic Perspective, Precious. If A Human Disagrees With You, Let Him Live. In A Hundred Billion Galaxies, You Will Not Find Another.

The Sacred Truth Of Science Is That There Are No Sacred Truths.
