The relationship between criticality and creativity is commonly misunderstood. Critical and creative thought are both achievements of thought. Creativity masters a process of making or producing, criticality a  process of assessing or judging. The very definition of the word  “creative” implies a critical component (e.g., “having or showing  imagination and artistic or intellectual inventiveness”). When engaged  in high-quality thought, the mind must simultaneously produce and  assess, both generate and judge the products it fabricates. In short,  sound thinking requires both imagination and intellectual standards.  Throughout this guide we elaborate on the essential idea that  intellectual discipline and rigor are at home with originality and  productivity, and also that these supposed poles of thinking (critical  and creative thought) are inseparable aspects of excellence of thought.  Whether we are dealing with the most mundane intellectual acts of the  mind or those of the most imaginative artist or thinker, the creative  and the critical are interwoven. It is the nature of the mind to create  thoughts, though the quality of that creation varies enormously from  person to person, as well as from thought to thought. Achieving quality  requires standards of quality — and hence, criticality.
We  believe that creative thinking, especially, must be demystified and  brought down to earth. For this reason, we deal with it in this guide  not only in terms of its highest manifestation (in the work of  geniuses), but also in its most humble manifestations (in everyday  perception and thought).
There  are ways to teach simultaneously for both creative and critical  thinking. To do so requires that we focus on these terms in practical,  everyday contexts, that we keep their central meanings in mind, that we  seek insight into how they overlap and interact with one another. When  we understand critical and creative thought truly and deeply, we  recognize them as inseparable, integrated, and unitary.
