At a Glance
- The wordContinuous parts belong to one bodily continuum; contiguous parts merely touch. The author uses that difference to reject separate material shells as the structure of Heaven.
- In the bookThe argument challenges a teaching arrangement treated as physical reality, then questions why a separate first movable sphere should supply a motion Heaven might possess internally.
- In this edition“First movable sphere” follows primum mobile. The later phrase “first mover” in the same canon refers to that sphere as mover of lower heavens, not to God as an unmoved first cause.
- A place to readCanons 237–238 make a paired criticism; 239–240 immediately retain the higher hierarchy of spiritual government.
Meaning
Continuus and contiguus are not interchangeable words for nearness. The author's distinction concerns whether one material body is divided into genuinely separate shells or remains a continuum with differentiated parts. His objection is not to every useful distinction of regions, ranks, or powers. It is to converting those differences into separate material surfaces without adequate need. Primum mobile names the proposed first moved body above the lower heavens; the question is about the location and transmission of motion, not about abolishing the Creator.
Use in the book
The continuity claim has an early foundation in canon 21. The world's original moist material can flow, be refined, and extend into one continuous fabric. Its continuity is attributed to moisture acting as glue and solder. Canon 77 later calls the whole air Heaven, a medium connecting scattered natures and transmitting their powers. These passages prepare a cosmos whose differences are joined rather than isolated. They do not, by themselves, eliminate the three regions introduced in canon 10: differences of order and excellence remain central.
The immediately preceding astronomical sequence in 233–236 adds a dynamic reason for restraint. Different bodies can move proportionately without identical motion; varying heavenly configurations can influence lower natures. Such differentiation need not establish separate material orbs. Canon 237 states the point directly: Heaven's parts are continuous, not merely contiguous. The world is Nature's work rather than a construction whose divisions have been imposed for a lesson. Those first dividing the ethereal region into many circles and orbs, the author says, pursued ease of teaching more than truth.
His alternative is not an undifferentiated equality of all celestial parts. One body, continuous in matter yet diverse in dignity and power, could suffice. The claim thus separates material unity from rank and function. This distinction also limits the appeal to simplicity: Nature's love of unity does not forbid the many bodies and natures discussed elsewhere. It argues against a particular multiplication of physically separated heavens.
The author then admits ignorance of the actual laws of stellar movements. The polemic against a masked Astrology targets explanatory constructions produced under that ignorance. Nevertheless he asserts that a continuous Heaven can provide laws congruent with human reason. The argument is not a rejection of intelligibility, measurement, or every mathematical aid. It rejects making a model's divisions authoritative over Nature merely because they help teaching.
Canon 238 extends the criticism to a rapid first movable sphere above the heavens. If that body may be assigned a principle of movement, why deny such a principle to the heavenly globe itself? Why posit an external cause where an internal one can suffice? This is an explanatory challenge, framed as questions, not a supplied mechanical account of celestial rotation. It removes an allegedly unnecessary intermediate body, not the entire hierarchy of causation. Canons 239–240 immediately resume communication from the Archetype through Intelligences and heavenly orders. Reading them together prevents the first-movable argument from being mistaken for an assertion that the cosmos has no divine source or higher spiritual governance.

Translation in this edition
Canon 237's contrast of partes continuas and non contiguas is translated “continuous, rather than merely touching, parts.” “Separated in matter and distinguished by surfaces” follows materiâ separatos & superficie distinctos and gives the objection its precise target. Astrologia in this context encompasses the explanation of heavenly motions; the modern note warns against forcing a later astronomy/astrology boundary upon the term. In 238 “that first mover” corresponds to primo illi motori, pointing back to primum mobile. The source has not suddenly introduced a second discussion of God under the same English phrase.
