Theory In Practice is a Lovian political essay by Yuri Medvedev, published August 27th, 2010 by The House Publishers. It is a response to the ongoing debates between various people who call themselves socialist in one way or another. The base premise of the work can be summarized as "any (socialist) policy needs a theoretical base in order to be consistent". Medvedev argues that socialism should be more than just a political view. The main reason for Medvedev to write the work was the publication of Californication by Ferenc Szóhad.
