About this Journal

Philosophy, Theory, and Practice in Biology (PTPBio) is a peer-reviewed, open-access, online journal that aims to publish work from philosophers of science and theoretically-inclined biologists, and to encourage interactions across disciplinary boundaries. Our goal is to foster a broader conception of what it means to reflect on and analyze biological theory and method, both scientifically and philosophically.
