"These syllables, about 2,300 in number, were mixed together and then drawn out by chance and used to construct series of different lengths, several of which each time formed the material for a test"
About this Quote
Ebbinghaus is describing a brutally simple trick that changed psychology: strip language of meaning so memory can be measured like a physical phenomenon. Those “syllables” are his famous nonsense syllables - controlled, interchangeable units designed to short-circuit association, imagery, and personal relevance. The clinical phrasing (“mixed together,” “drawn out by chance”) isn’t just lab talk; it’s a manifesto. He’s insisting that the mind can be studied with the same suspicion of bias and the same appetite for repeatability that nineteenth-century science prized.
The subtext is defensive, almost prosecutorial. Memory research before him leaned on introspection, anecdotes, and literature’s authority about the mind. Ebbinghaus anticipates the obvious critique - that experimental material will smuggle in meaning - and answers it by turning his stimuli into something like shuffled cards. Chance becomes a moral instrument: if the sequence is random, the results can’t be accused (as easily) of being curated to fit a theory.
Context matters: this is late-1800s psychology fighting for legitimacy as a laboratory science, and Ebbinghaus is largely working alone, often using himself as the subject. That constraint makes the method’s austerity even more strategic. By minimizing interpretation in the materials, he maximizes the credibility of the numbers that follow - savings, repetitions, forgetting curves. The prose reads dry because dryness is the point: it performs objectivity, and in doing so, sells a new kind of psychological truth.
