Early modern experimentation on live animals.

Area of Science:

• History of Science
• History of Medicine
• Physiology

Background:

• Vivisection has ancient roots, but early modern period (17th-18th centuries) saw a resurgence.
• Key foundational works include Aselli's on milky veins (1627) and Harvey's on blood circulation (1628).

Purpose of the Study:

• To examine notable vivisection cases and practitioners from Aselli to Stephen Hales (1727).
• To analyze the expanded practices, epistemic motivations, and methodological awareness in early modern vivisection.
• To explore the ethical considerations and perceived medical applications of these experiments.

Main Methods:

• Historical analysis of primary and secondary sources on early modern vivisection.
• Focus on key figures: Johannes Walaeus, Jean Pecquet, Marcello Malpighi, Reinier de Graaf, Richard Lower, Anton Nuck, Anton de Heide.
• Examination of experimental techniques and discussions on animal welfare and scientific validity.

Main Results:

• Early modern vivisection experiments were extensive, sophisticated, and technically skilled.
• Practitioners demonstrated awareness of challenges, including animal suffering and generalizing results to humans.
• Despite ethical discomfort, experiments were deemed epistemically indispensable and potentially medically valuable.

Conclusions:

• Early modern vivisection significantly advanced scientific understanding and experimental methodology.
• These practices represent a crucial, often overlooked, chapter in the history of experimentation on living organisms.
• The ethical debates and methodological considerations from this era remain relevant to scientific inquiry.
