The conclusion reminds the reader of the goals of the book and suggests the practice of fragment writing as a way of enriching their ways of engaging with a notion that deserves to be treated, not in linear but in complex ways. The author illustrates concretely how he has himself ‘performed’ the three elements of a diversity of thoughts, criticality of criticality and unthink and rethink in his work over a period of two years. A figure summarising the main points made in the book is proposed as a convenient ‘toolbox for out-of-the-box ideas’.
