In the opening chapter, we explain the importance of engaging critically with social entrepreneurship. We underline the need to make an incisive assessment of social entrepreneurship through the way we (still) publish, critique and imagine books in this field. To all those who want to embark on the path of social entrepreneurship, or are simply curious to hear more about the buzz surrounding social entrepreneurship, we say be aware: we need critique, and we need it now! The affirmative critiques we offer to social entrepreneurship are not based on a priori judgements of social entrepreneurship performed from afar, but are intimately related to specific, phenomenological events and observations. Furthermore, we recapitulate how this book draws upon and intervenes in the critical reception of social entrepreneurship. The chapter ends with an overview of the various chapters and the various critical perspectives and themes they draw on and address.
