Abstract
Marjorie Grene's work expresses the conviction that what is called "the new philosophy of science" will not become viable until it is rooted in an understanding of the knower and the known which breaks with the familiar Cartesian dualisms. In order to provide this understanding, she has sought to restore central significance to the phenomenon of life -- to the distinctive ways in which animals, including human beings, perceive and act in their worlds. It is argued that her fundamental premise is that humans, as living beings, bring a shared experience of the world with them into scientific activity. On this basis, she is able to show how scientific objectivity may be seen as a form of pre-scientific exploration and how the scientifically known world may be seen as the pre-scientific life-world interpreted and enriched in scientific terms.
