"Edible substances evoke the secretion of thick, concentrated saliva. Why? The answer, obviously, is that this enables the mass of food to pass smoothly through the tube leading from the mouth into the stomach"
About this Quote
Pavlov’s deadpan “obviously” is doing more work than it seems. On the surface, he’s describing a plumbing problem: food is a mass, the throat is a tube, lubrication helps. But the rhetorical move is a quiet declaration of scientific temperament. He’s not merely naming a bodily function; he’s modeling a worldview in which behavior (even the intimate, messy kind) can be reduced to mechanism, purpose, and measurable output.
The intent is strategic. By starting with “edible substances” rather than “food,” Pavlov strips the scene of comfort and culture. Dinner becomes stimulus. Saliva becomes secretion. The human mouth is no longer the gateway to pleasure or speech; it’s an entry point in a system of flows. That clinical diction clears emotional clutter so he can argue that “obvious” explanations should be physiological before they’re psychological. In the era of introspection-heavy accounts of mind, Pavlov’s point lands like a corrective: start with the body, trace the reflex, then talk about “mind” if you still need it.
Subtext: if this is obvious, then your cherished sense of choice might be less central than you think. Once you accept that salivation has a functional rationale, you’re halfway to accepting that salivation can be hijacked by association, training, prediction. The throat “tube” isn’t just anatomy; it’s a metaphor for his project: turn life into a tractable pathway where stimuli enter, responses emerge, and mystery gets demoted to missing data.
