The Hedgehog and the Fox is an essay by the British academic philosopher Isaiah Berlin, which classifies thinkers into two kinds, those who know lots of different things, and those who base their thinking on a single grand idea. The title came from a fragment attributed to the ancient Greek poet Archilochus, translated as, “A fox knows many things, but a hedgehog one important thing.” Well, we don’t anything important about all that. However, one thing we do know is that SullivanPerkins is moving its offices in January, and this is the occasion of a massive clean out (and considerable nostalgia). Among the items turning up: collections of the SullivanPerkins summer t-shirts we produced for many years as self-promotional giveaways for clients and friends. The very last t-shirt we did, after the crash of 2008, acknowledged the fact that we had been compelled to downsize in 2009 — and the t-shirt itself was a miniature. What possible use could we find in 2016 for our newly discovered left-over samples of 09’s miniature t-shirt? It turns out that account manager Carly has a pet hedgehog. The one big thing that this particular hedgehog now knows is what it feels like to receive a SullivanPerkins summer t-shirt as a Christmas gift.
