This book shows that “Every change is caused” is knowably necessary,
contrary to Hume. That changes everything in subsequent philosophy;
for the false dichotomy between epistemically necessary truths and
truths informing us of what exists arises only as a result of Hume. Also
false is the common premise of rationalism and empiricism: knowledge
of necessary truth cannot come from experience. Causal Realism
analyses necessary truth, for the first time, as a function of general truth
conditions. Doing so allows it to explain our knowledge of logic and
mathematics, provide non-Kantian foundations for empirical knowledge,
and show why post-fregean methods have not reduced philosophic
disagreement and paradox. Its ground-breaking arguments make use
of overlooked contributions of two modern classical realists, Maritain
and Simon, who were consistent with their tradition but greatly advance it in response to modern problems and insights.
