Economics is part of the web of human knowledge that spans the totality of human experience. This web of knowledge is the greatest resource humans have when it comes to facing the challenges of the future. When adopting this broad, human ecology view, the economist aims to contribute to the growth of knowledge generally. It includes being willing to assess the strengths and weaknesses of one’s professional area by, in particular, paying attention to the nature and quality of that which passes through the boundaries of the field, i.e. imports from and exports to other disciplines. It also includes being open to insights from other fields that may contradict or supplement the economist’s own beliefs and practices.1
