1 " The conflict between science and religion has a single and simple cause. It is the designation as religiously canonical of any conception of the material world open to scientific investigation....As a matter of fact, most of the dogmatic religions have exhibited a perverse talent for taking the wrong side on the most important concepts of the material universe, from the structure of the solar system to the origin of man. The result has been constant turmoil for many centuries, and the turmoil will continue as long as religious canons prejudge scientific questions. "
2 " My citizen activism is a direct outgrowth of a classical and fiscally conservative training in economics at Harvard. It is a perspective rooted in one of the most important concepts in economics - the need for government intervention in the presence of a market failure. "
