MATHEMATICS (MS 1-278)
Four given rays may be crossed by how many rays? The analysis of the Four-ray problem requires a consideration of continuity which in its primitive, i.e., simple, sense has the form of time. Time as a determination of actuality (later see annotation CSP dissents). Definition of terms, e.g., instant, gradations. "I will not take up more of this book with the subject of discrete quantity But I refer to a similar book labelled 'All Pure Quantity merely ordinal' [MS. 224] for more about it."
