The grand aim of all science is to cover the greatest number of empirical facts by logical deduction from the smallest number of hypotheses or axioms.
The sum of intelligence on the planet is a constant; the population is growing.
[W]e shall continue to have a worsening ecologic crisis until we reject the Christian axiom that nature has no reason for existence save to serve man.
Ethical axioms are found and tested not very differently from the axioms of science. Truth is what stands the test of experience.
