Quotation from Treatise on Light by Christiaan Huygens
“here the Principles are verified by the conclusions to be drawn from them; the nature of these things not allowing of this being done otherwise.”
Treatise on Light, Preface, trans. Silvanus P. Thompson (1912)
Huygens contrasts the method of physics with that of geometry, where propositions follow from fixed principles.
