One of the most discussed qualities of design is 'simplicity'. Almost every designer has simplicity as an ambition and first principle with all their design work. To make designs simple seems to be a goal in itself. But what is simplicity? We have over the years seen a lot of articles and books examine the concept from different perspectives. Quite recently Per Mollerup published a new book "Simplicity -- a matter of design". I have found this book to be one of the best so far on this topic. Mollerup's investigation into simplicity is not a 'simple' preaching of the necessity of simplicity, he approaches the concept with more care and curiosity than most, and deals with its richness in a way that so far has been unusual.
Mollerup not only explains his view of simplicity, he also questions existing and 'simplistic'
understandings of the concept. Apart from giving some fundamental definitions of simplicity, he also examines the relationship between simplicity and functionality, aesthetics, and ethics.
Mollerup's book is also visually stunning. The images of designs that he has chosen to complement the text are quite amazing in their own right. I can see the book used as a textbook since it so carefully try to exemplify and visualize the conceptual examinations that the text is engaged with.
If the examples and the insights concerning ultimate particular designs and their relationship to simplicity is the strength of the book, personally I might have wanted some more depth in the conceptual and philosophical examination of simplicity in the text. But I do not see that as a problem with the book, instead I can see how this books opens up for and even require such further investigations.
I would recommend this book to anyone who is interested in design and especially in what simplicity means in design. The definitions and examples will enlighten any reader and in a productive way challenge their own conceptions of what simplicity means.
