Dimension-by-Dimension Evidence

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

Time

On Forms (Peri Ideōn)

The c. 430 BCE moment of Democritus's mature atomic philosophy.

Space

On Forms (Peri Ideōn)

Abdera and the broader pre-Socratic Greek philosophical setting.

Matter

On Forms (Peri Ideōn)

The atoms whose geometrical forms the treatise treats.

Observer

On Forms (Peri Ideōn)

The atomic-philosophical natural philosopher as proper subject.

Energy

On Forms (Peri Ideōn)

The mechanical-atomic energies of interactive geometrical configurations.

Information

On Forms (Peri Ideōn)

The atomic-geometrical-philosophical content of the treatise.

Internal Tensions

Where each work's argument pulls against itself.

On Forms (Peri Ideōn)

On Forms is lost; the primary-secondary-quality distinction has remained central to philosophy from Galileo onward. The proper-modern-physical understanding of atoms differs substantially from Democritus's purely-geometrical conception.
