“It is indeed a matter of great difficulty to discover, and effectually to distinguish, the true motions of particular bodies from the apparent; because the parts of that immovable space, in which those motions are performed, do by no means come under the observation of our senses.

Isaac Newton

About This Quote

Source Treatise on the Motion of Bodies, 1687 (Principia Mathematica)

True motions differ from apparent ones; we must infer hidden dynamics using indirect evidence and reasoning.

In simple terms: Real motion is hidden; we deduce it by analysis.

Key Takeaway

Use careful observation and logical inference to uncover unseen forces.
