Adding value to the invisibility of typefaces

In the beginning was the word. Then came the writing, almost universal way to convey a message in a sustainable way, a thought, an emotion. There is nothing better that writing to visualize something abstract. Designers use writing as a tool to bring the imaginary to the real world. Even as typography has long been understood as the heart of graphic design, it perfectly emphasizes the adage that good design is a design that is not seen. For most readers, typefaces are neither understood nor effectively analyzed but only interpreted (often instinctively) as a tool that supports the reading, despite its omnipresence around us and constantly renewed use. Yet that design work remains transparent to the public. So how does one develop something that is invisible?
