Abstract
I present five theses to characterize and argue for "Instrumental Realism," a realism wedded to what we do with instruments, and not what our theories say: The Independence Thesis: Questions about realism are independent of questions about meaning. The Intervening Thesis: Our ability to produce consistent effects with our instruments provides one guarantee that we are engaged with the real world. The Historical Thesis: If the descriptions of what we know and do are of something real, then it will be possible to trace a history from earlier antiquated names and actions to current usages. The Instruments-Do-Not-Always-Work-Right Thesis: Since instruments do not always work right, a successful instrumental intervention cannot be a social construct. The Tinkering Thesis: Since instruments are created by tinkering, we should not take any claim that generalizes away from our instrumental practice realistically.
