• I was very young when I prepared those prints. I suspect the reason I couldn't celebrate the floating world was that I couldn't bring myself to believe in its worth. Young men are often guilt-ridden about pleasure, and I suppose I was no different. I suppose I thought that to pass away one's time in such places, to spend one's skills celebrating things so intangible and transient, I suppose I thought it all rather wasteful, all rather decadent. It's hard to appreciate the beauty of a world when one doubts its very validity

• Creativity is the generation and initial development of new, useful ideas. Innovation is the successful implementation of those ideas in an organization. Thus, no innovation is possible without the creative processes that mark the front end of the process: identifying important problems and opportunities, gathering relevant information, generating new ideas, and exploring the validity of those ideas.

• Science has long been in the value business. Despite a widespread belief to the contrary, scientific validity is not the result of scientists abstaining from making value judgments; rather, scientific validity is the result of scientists making their best efforts to value principles of reasoning that link their beliefs to reality, through reliable chains of evidence and argument.
