Modern Typography, authored by Robin Kinross, posits a core argument: modernity is rooted in rationality—an informational order beginning with the Enlightenment that pursues clarity and accessibility. This principle perfectly mirrors the ultimate law of flag design. The grid systems, geometric rigor, and functionalist principles detailed in the book constitute the very modernist foundation underlying classic designs such as the Swiss national flag or the Canadian Maple Leaf flag. It reveals that whether in text or in a flag, exceptional modern visual communication stems from the same spirit: using the most rational form to achieve the most efficient public communication.
