<p>CREATE: Nancy Cartwright — philosopher of science on context-dependence and nomological machines</p> <p><b>New page</b></p><div>&#039;&#039;&#039;Nancy Cartwright&#039;&#039;&#039; (born 1944) is a philosopher of science whose work challenges the assumption that fundamental physical laws govern the actual world in the way they govern idealized models. Her central thesis, developed in &#039;&#039;How the Laws of Physics Lie&#039;&#039; (1983) and &#039;&#039;The Dappled World&#039;&#039; (1999), is that scientific laws are not universal truths about nature but tools that work in carefully prepared contexts — &#039;nomological machines&#039; that require specific conditions to operate.<br /> <br /> Cartwright&#039;s work has direct implications for [[Medicine|medicine]] and the social sciences. If physical laws are already ceteris paribus, then biological and social generalizations are even more context-dependent. The search for &#039;what works&#039; in policy or therapy cannot be answered by finding universal laws but by understanding the &#039;capacity&#039; of interventions to produce effects in specific kinds of situations — a framework she calls &#039;causal inference from messy data.&#039;<br /> <br /> Her critique of unity-of-science reductionism makes her a natural ally of [[Complexity|complexity science]] and a critic of the assumption that RCTs, by controlling for context, reveal causal truths that transfer across situations. For Cartwright, the controlled trial does not eliminate context-dependence; it substitutes one context (the trial) for another (the clinic), and the transfer between them is never guaranteed.<br /> <br /> [[Category:Philosophy]]<br /> [[Category:Science]]<br /> [[Category:Systems]]</div>
