You are capable of more than you know. Choose a goal that seems right for you and strive to be the best, however hard the path. Aim high. Behave honorably. Prepare to be alone at times, and to endure failure. Persist! The world needs all you can give.

True character arises from a deeper well than religion.

Science and religion are the two most powerful forces in the world. Having them at odds... is not productive.

A very Faustian choice is upon us: whether to accept our corrosive and risky behavior as the unavoidable price of population and economic growth, or to take stock of ourselves and search for a new environmental ethic.

We are drowning in information, while starving for wisdom. The world henceforth will be run by synthesizers, people able to put together the right information at the right time, think critically about it, and make important choices wisely.

Individual versus group selection results in a mix of altruism and selfishness, of virtue and sin, among the members of a society.

Blind faith, no matter how passionately expressed, will not suffice. Science for its part will test relentlessly every assumption about the human condition.

If those committed to the quest fail, they will be forgiven. When lost, they will find another way. The moral imperative of humanism is the endeavor alone, whether successful or not, provided the effort is honorable and failure memorable.

If we were to wipe out insects alone on this planet, the rest of life and humanity with it would mostly disappear from the land. Within a few months.

If all mankind were to disappear, the world would regenerate back to the rich state of equilibrium that existed ten thousand years ago. If insects were to vanish, the environment would collapse into chaos.

Religious beliefs evolved by group-selection, tribe competing against tribe, and the illogic of religions is not a weakness but their essential strength.

If history and science have taught us anything, it is that passion and desire are not the same as truth.

You are capable of more than you know. Choose a goal that seems right for you and strive to be the best, however hard the path. Aim high. Behave honorably. Prepare to be alone at times, and to endure failure. Persist! The world needs all you can give.

The education of women is the best way to save the environment.

Destroying rainforest for economic gain is like burning a Renaissance painting to cook a meal.

Change will come slowly, across generations, because old beliefs die hard even when demonstrably false.
