More than ten years ago it was said insistently in university classrooms, almost as a slogan, that Leisure and Recreation Studies was a field under construction. Today the same cannot be said. It is undoubtedly a growing and rapidly expanding field. The proliferation of questions in the field has become masterful: Leisure! Free time?! Recreation?! What are they, what do they refer to, what can be said about and from them? What is your relationship with politics, with the economy, with education? In what sense are matters really important? What is its true significance for existence? Our moment has the imperative responsibility to show with Robert Louis Stevenson that idleness "does not consist in doing nothing, but in doing many of the things that are not accepted in the dogmatic forms of the ruling class." For this reason, once the critical stage of justification of its existence has passed, the academics of the field have undertaken the task of beginning to speak from this multidisciplinary knowledge, to explain phenomena of social reality and, of course, to show in what sense these can become something other than what they are conventionally believed to be. The objective of this book is to present to the academic community (within and outside the field of leisure and recreation studies) various analyzes about issues that inevitably cross its core, which is why it is a source of concrete proposals to intervene with pedagogical practices and with research in different contexts, from the most institutional to the most unusual.
