There is a spectre haunting the sciences -- the spectre of dialectical materialism!  Students and scholars alike are alienated from the rich tradition of Marxist approaches to and intervention in their fields in spite of vulgarized vestiges from this era still present and popular in their fields. In this event, we'll survey and synthesize the history of radical approaches to science in an effort to understand how, in spite of significant intellectual victories throughout the 20th century, it has been marginalized out of scientific practice. Through this analysis, we'll discuss the task of radical science today and the necessity of movement-building toward this end. While this will be a little lecture-y, it will also be very discussion-based and very informal. This event will commemorate the one year anniversary of the Chicago chapter of SftP.
