Opticks

Isaac Newton
1704 (English first edition); 1706 (Latin) · English (with Latin edition)
Scientific treatise in three books, with Queries appended · Early modern natural philosophy / experimental method

The corpuscular theory of light, Newton's rings, the spectrum — and the famous Queries that speculatively probe gravity, ether, life, and the nature of God

Dimension-by-Dimension Evidence

What each work's passages reveal about its stance on each of the six dimensions.

Time

Opticks

Absolute Newtonian time. The optical experiments presuppose a uniform temporal background.

Space

Opticks

Absolute Newtonian space. Light travels through absolute space at definite velocities.

Matter

Opticks

Corpuscular — light itself is composed of small bodies. Newton's mechanical philosophy of matter is consistent across Principia and Opticks.

Observer

Opticks

The Newtonian observer is the experimental natural philosopher using instruments to extend observation. Active, plural in the scientific community.

Energy

Opticks

Conserved in mechanical interactions; the precise modern concept of energy comes later.

Information

Opticks

Real natural information is recovered through careful experiment. Newton's Christianity is genuine; personal information conserved across death.

Internal Tensions

Where each work's argument pulls against itself.

Opticks

The corpuscular theory of light was overturned in the nineteenth century by the wave theory (Young, Fresnel) and then partially recovered in quantum mechanics (photons). The Queries' speculative metaphysics has been read variously as Newton's deepest philosophical thinking or as careful self-protection against the rigour Newton imposed on his published Principia. Modern Newton scholarship (I. Bernard Cohen, Niccolò Guicciardini) emphasises that Newton was a more speculative metaphysician than the Principia's public method suggests.
