The image of Proust’s madeleine, a spongy almond-flavored cookie baked in a press to look like a scallop shell, a delight with an afternoon cup of tea or coffee, has become an icon for this reclusive writer. But what is Proust telling us in this passage? All memories are not created equal, he suggests, some are imprinted more strongly than others. One can have a very sharp recollection of a specific experience from one’s childhood, and still have forgotten entirely what one had for breakfast in the morning. Moreover, the long-past recollection need not even be associated with some objectively significant event, something traumatic, or happy, or historical. Second, he is pointing to the role that smell and taste play in memory, which may in fact be very intense but is not generally closely associated with memory. Third, he is noting that memory and its clarity and detail depend a lot on the mood of the individual, both at the time of the initial experience and at the time of occurrence.
One can struggle to recollection without success, and then the memory can come back suddenly, flooding the imagination of the rememberer, triggered by the strangest coincidence–the cup of linden-flower tea and the cookie, for instance. In our age, memory is facilitated greatly by artificial intelligence, by the Internet and computerized search programs. But the purely human memory has a very curious search program. The way we order and collect thoughts and memories is not entirely logical, and it links to all the senses–those of vision, touch, taste and sound. Our mind seems to act like a great sewing machine, stitching things together for reasons that may not immediately be present but which generally relate to the synchronization of the senses.
Proust called this kind of memory memoire involuntaire -- pretty much the opposite of the kind of thing you can Google search for.
