System of the world
2) Newtonianism After newton
Newton as Physicist
Newton on the ontinent
3)Newtonianism outside of Physics
His way of thought was similar to that of Descartes, also looked for a mathematical explanation just not
as bold of hypothesis. Called his way “analysis and Composition”. Do the testing and analysis, then
compare certain laws and understanding. Claims his method was “deduction from the phenomena”
compared to Descartes even though he induces.
Deduction = general > specific, truth preserving inferences, we are sure conclusion has truth
Induction = observation > general, observe many cases and make an induction, might lose truth, while
looking for the generality
Descartes always based is ideology on the fact that there needs to be contact in order for action to
happen. (screws for magnets). While Newton didn’t strive to understand and explain the phenomena.
He observed and drew rules of behavior.
“Rules of Reasoning in Philosophy” added in later editions of Principia to let others understand his
-Metaphysical Presuppositions (all things composed of the ideology)
Commitment to determinism that all actin happen for a reason.
-Newton’s “System of the world”
-first law – law of inertia, preservance of motion unless there is change
