There is an Arabic saying that the soul travels at the pace of a camel. While most of our self is led by the strict demands of timetables and diaries, our soul, the seat of the heart, trails nostalgically behind, burdened by the weight of memory. If every love affair adds a certain weight to the camel's load, then we can expect the soul to slow according to the significance of love's burden.

This interactive essay presents the ladder of abstraction, a technique for thinking explicitly about these levels, so a designer can move among them consciously and confidently.
