De Harmonie van het Dierlijke Leven: De Openbaring van Wetten

In a spirited 1848 inaugural lecture, a newly appointed professor confronts the fashionable habit of explaining animal physiology through teleology rather than causality. He points to the unmistakable order of planets, ecosystems, and bodily functions, urging that such harmony should inspire rigorous investigation, not a shortcut to purposeful speculation.

The address outlines a methodological program that relies on careful observation, experimentation, and logical deduction to uncover the true laws governing living matter. Vivid illustrations—ranging from the predictable paths of celestial bodies to the rhythmic cycles of respiration—show how cause‑and‑effect can replace vague notions of design. By the close of this opening section, listeners are left with a clear invitation to pursue a science of the animal world that honors both its elegance and empirical rigor.
