Mnemonics as signs of memory: semiotics and agency

This paper engages the question of the extended mind hypothesis, specifically in terms of memory and mnemonics. I use the case of an external object which is set to trigger a memory internally, but is not the memory, to explore the idea of extension versus distribution. I use the example of tzitzit, which is a garment worn by observant Jewish men, where is states in scripture that seeing the tassels attached to the garment are supposed to trigger a specific memory. The point of the essay is that extension is merely a metaphysical commitment, and that this commitment leads to some ethical issues.
