“A true scientist is bored by knowledge; it is the assault on ignorance that motivates him - the mysteries that previous discoveries have revealed.”
“Still, our knowledge of the planets was meager, and where ignorance lurks, so too do the frontiers of discovery and imagination.”
“The assumption that a whole system can be made to work better through an assault on its conscious elements betrays a dangerous ignorance. This has often been the approach of those who call themselves scientists and technologists.”
“True ignorance is not the absence of knowledge, but the refusal to acquire it.”
“... informed ignorance provides the natural state of mind for research scientists at the ever-shifting frontiers of knowledge. People who believe themselves ignorant of nothing have neither looked for, nor stumbled upon, the boundary between what is known and unknown in the cosmos.”
“The final discovery is the discovery of knowledge.”
