Observations About Digestion
Van Helmont wrote extensively on the subject of digestion. In Oriatrike or Physick Refined (1662, English translation of Ortus medicinae ...), van Helmont addressed earlier ideas on the subject, such as that food was digested due to the body's internal heat. If such was the case, van Helmont argued, how could cold-blooded animals live? His own opinion was that digestion was aided by a chemical reagent, or "ferment", within the body, such as inside the stomach. Harré suggests that in this way, van Helmont's idea was "very near to our modern concept of an enzyme." van Helmont proposed and described six different stages of digestion.

“The truth is, the Science of Nature has been already too long made only a work of the brain and the fancy: It is now high time that it should return to the plainness and soundness of observations on material and obvious things.”
—Robert Hooke (1635–1703)
“Memory is like a purse,—if it be over-full that it cannot shut, all will drop out of it. Take heed of a gluttonous curiosity to feed on many things, lest the greediness of the appetite of thy memory spoil the digestion thereof.”
—Thomas Fuller (1608–1661)
