Importantly, the ready-to-hand only emerges from the prior attitude in which we care about what is going on and we see the hammer in a context or world of equipment that is handy or remote, and that is there "in order to" do something. In this sense the "ready-to-hand" is "primordial" compared to that of the present-at-hand. The term primordial here does not imply something Primitive, but rather refers to Heidegger's idea that Being can only be understood through what is everyday and "close" to us. Our everyday understanding of the world is necessarily a part of any kind of scientific or theoretical studies of entities — the present-at-hand — might be. Only by studying our "average-everyday" understanding of the world, as it is expressed in the totality of our relationships to the ready-to-hand entities of the world, can we lay appropriate bases for specific scientific investigations into specific entities within the world.
