Degrees

gradus, “degrees”; à gradu ad gradum, “from degree to degree”; gradus comparationis, “degrees of comparison”

Degrees are the intervening conditions by which materials become more subtle, coarse, volatile, fixed or enduring in heat.

Meaning

Degrees are ordered differences within a continuum of common matter. Heaven and earth occupy widely separated conditions, but each element is internally graded, and neighbouring grades pass into one another more readily than remote extremes. This is how the four-element scheme becomes an account of possible transformation rather than a set of four impassable boxes (B1C04S003; B1C09S008).

The differences concern subtlety, coarseness, volatility and fixation, but degrees also appear in instructions about heat. A material’s preparedness and the heat applied must not be collapsed into one measure: the text varies fire to bring a subject through changing conditions (B1C03S001; B2C05S015).

Use in the book

The first water’s separation is described through a grammatical analogy. Subtle comes before coarse, thin before thick, as children learn positive, comparative and superlative. The point is sequence and relative order. The book does not provide a universal numerical scale assigning every material a scientifically measured degree of subtlety (B1C03S001).

The elemental chapters make the middle steps concrete. Thin water may fail to attack coarse earth, although it takes up a subtler salty earth. Nature has also mixed the grades together, so ordinary sight does not present them as stacked separate spheres; analysis reveals their different behaviours. The operator must therefore distinguish what a particular water can dissolve and how it must itself be altered before the next portion can follow (B1C04S004; B1C04S005).

The same order governs the later mineral genealogy and backward reduction. Vitriol, sulphur, arsenic, marcasite and metal receive their places according to increasing fixation; to return a refined metal one must restore suitable neighbouring portions in sequence. The author’s heating discussion similarly warns against jumping from an earlier degree straight into open fire. Degrees thus discipline both the interpretation of material names and the timing of practical intervention (B1C23S035; B1C23S052; B2C05S015).

Translation in this edition

Gradus can name a step, degree or ordered condition; the phrase à gradu ad gradum stresses passage from one to the next. Gradus comparationis supplies the explicit comparison with grammatical degrees, which is an analogy for order rather than a numerical instrument (B1C17S003; B1C03S001).

When a degree is attached to fire, a bath, sand or another heating condition, it belongs to a specific operation. Such local gradations should not be assigned modern temperature values unsupported by the edition. Keeping them relative is necessary to preserve the text’s reasoning without inventing calibration (B2C05S015).
