Intellectuals and scholars tend to believe that ideas come first which then lead to new political, social, economic, psychological realities. This does happen, but it is the exception. As a rule, theory does not precede practice. Its role is to structure and codify already proven practice. Its role is to convert the isolated and “atypical” from exception to “rule” and “system”, and therewith into something that can be learned and taught, and, above all, into something that can be generally applied. Theory organizes the New Realities; it rarely creates them.
– Peter F. Drucker in The New Realities
