The whole difficulty of philosophy seems to consist in this—from the phenomena of motions to investigate the forces of nature, and then from these forces to demonstrate the other phenomena.

"God is the same God, always and everywhere. He is omnipresent not virtually only, but also substantially; for virtue cannot subsist without substance."
"The cause of gravity is what I do not pretend to know."
"I was born in the year of the comet."
"For it is the property of true philosophy to deduce the causes of all natural effects from the simplest possible principles."
"To explain all nature is too difficult a task for any one man or even for any one age."

Science's central challenge, as Newton frames it, is a two-step loop: observe what moves and how, then reason backward to uncover what forces drive that motion. Once those forces are identified, use them to predict other behaviors not yet observed. It is the foundation of the scientific method—induction from evidence to principle, then deduction from principle to new discoveries—described centuries before we had that vocabulary.
Newton literally executed this method in his masterwork, the Principia Mathematica. He started from observed planetary motions—Kepler's documented orbital regularities—and worked backward to universal gravitation as their cause. He then used that single force law to mathematically derive the tides, comet trajectories, and Earth's shape. His career in optics followed the same structure: light's behavior led to the force of refraction, which explained the spectrum.
In the 17th century, European natural philosophy was overthrowing Aristotelian explanations—which described the world in terms of qualities and purposes—with mathematical, force-based accounts. Descartes had tried to explain motion through vortices and contact forces alone. Newton's generation faced urgent questions: can nature's hidden mechanisms be known at all? His quote stakes a position: yes, through rigorous mathematical inference from motion to force, not speculation.
