The originality of Suppes’ approach resides in the fact that he proposes to formulate geometry as a practice of constructions, comparable to Hjelmslev’s work yet quite distinct. A construction is here to be understood in the elementary sense of producing drawings or diagrams, using certain instruments, such as a ruler and/or a compass, and not in the modern sense in foundational terms, i.e., a constructive, axiomatic foundation for geometry.
