Over the past fifteen years, a new dimension to the analysis of science has emerged. Feminist theory, combined with the insights of recent developments in the history, philosophy, and sociology of science, has raised a number of new and important questions about the content, practice, and traditional goals of science. Feminists have pointed to a bias in the choice and definition of problems with which scientists have concerned themselves, and in the actual design and interpretation of experiments, and have argued that modern science evolved out of a conceptual structuring of the world that incorporated particular and historically specific ideologies of gender. The seventeen outstanding articles in this volume reflect the diversity and strengths of feminist contributions to current thinking about science.
