In today's special environment, therefore, the Foundation regards responsiveness to change as a cardinal virtue — this despite the fact that our long-held emphasis upon aid to the application of knowledge grows no easier in an age when discoveries are seemingly boundless in content and implication. Using the health field as an illustration, the professions, universities, governments, and private organizations have joined forces greatly to expand health knowledge, facilities, and services. Yet there lingers the problem of how to make these services more available to more people. It is a manpower problem to some degree, but simply additional manpower in the health and allied fields will not comprise an adequate answer. New methods must be discovered and developed for the improved provision of health care and there is a parallel need for modern education and communications to convey new findings to millions of Americans who can benefit from them.
