This Human is about the person who is doing the designing.
There are many great design books in existence that teach us about design process, tools and methods. With the increasing popularity of design thinking and human-centered design we've also seen more material discussing various aspects of the practice. One missing aspect, almost in an ironic twist, is what it takes to be the actual person who is doing the designing.
The name This Human is referring to that person. The person who needs to observe to gain insight, to makes sense of their observations in a way that isn't biased by their own world views. The person who needs to communicate in many different ways with many different intentions to communicate information which is often hard to access, difficult to grasp and just not that tangible. The person who is so passionate about having a positive impact they become exhausted one third of the way into their project. This book helps these people to learn more about themselves and how to think and be in their practice of design—to help them grasp all that is going on inside that then influences their creations.
