"We may best imagine the field of learning as a neatly divided allotment garden parcelled out in equal sections. In the center of every parcel there rises a tallish plant of the accepted doctrines in the speciality, surrounded by straight rows of carefully tested smaller plants whose affect of rather boring and sterile monoculture. It has long been known that powerful new impulses can rarely be expected to arise within the centers of each discipline. Specialists hesitate to venture out on the margins of their fields, where the ground tends to be slippery and they can easily muddy their scientific reputation. But it is precisely in those regions, near the �fences� between the parcel, where the footing is uncertain, that the young shoots of new knowledge flourish. To investigate them one must have courage to oppose prevailing doctrine, to leave the well-ordered beds and seek new ways into pathless regions. Thee offer a unique opportunity. In the wild strips interspersed among the disciplines, where stimuli from various professional fields meet, where, as it were, the superphosphate put on by one gardening neighbour mixes with the peat moss contributed by another, there is still hope of discovering new and hitherto unknown species. Almost always the seedlings of new insights spring up in the uncultivated interfaces between neighbouring scientists."
