The house, Whitehall, survived and is now owned and administered by the Colonial Dames of Rhode Island. As the headquarters of the International Berkeley Society, Whitehall boasts a comprehensive collection of early editions of Berkeley's works. These include a first edition of Alciphron, the book which Berkeley wrote during his stay in Rhode Island, inscribed "from the Author." Upstairs is a small research library with an impressive range of secondary literature on Berkeley, from the scholarly to the eccentric. (An example of the latter: Berkeley and the Paranormal.)
My duties were to live in the house, to raise the flag at dawn, lower it at dusk, to pursue my own scholarly research, and to give tours to any members of the public who managed to find their way there. Joining me in residence were my wife, Shelley, and 18-month-old daughter, Chloe.
It is an atmospheric place to stay. The property is bordered with dry-stone walls, and a garden of culinary and medicinal herbs faces one side of the house. Inside, the rooms are laid out as they might have been in Berkeley's time, with period furniture, books in English and in Latin, and 18th-century maps and portraits on the walls. Most of the house has no electric lighting so at night we lit candles which flickered in the cool evening breezes that blew in off the sea. A pendulum clock sitting on a bracket in the front parlor ticked noisily in the darkness.
Whether you find this claim plausible or not, it is not an accurate reflection of Berkeley's version of idealism. On the one hand, Berkeley's position is more extreme. He does not think that it is merely secondary qualities such as colors, sounds, and tastes which exist only as perceptions. Material objects such as tables, chairs, and planets also exist only as bundles of perceptions in people's minds. So if the falling tree is not seen or heard by anyone, then not only is there no sound, there is no tree! On the other hand, Berkeley's position has less radical consequences than one might think. Doesn't it imply, for example, that the furniture around you blinks out of existence each time you close your eyes? For Berkeley, an Anglican theologian and later a Bishop, the answer is no. The reason why not is encapsulated in the following 19th-century limerick:
There was a young man who said, "God
Must think it exceedingly odd
If he finds that this tree
Continues to be
When there's no-one about in the Quad."
"Dear Sir, your astonishment's odd.
I am always about in the Quad.
And that's why this tree
Will continue to be
Since observed by Yours faithfully, God."
Unlike most of the previous philosophers in residence at Whitehall, I am not a scholar of Berkeley per se. Instead my connection to Berkeley is via the subject matter of my research in the philosophy of science and the philosophy of mathematics. Specifically, I am interested in the link between methodology and ontology - in other words, that the way we evaluate different theories relates to what we end up believing exists.
For example, other things being equal we tend to prefer simpler theories over more complex alternatives. How simple is Berkeley's idealism? In one sense, it is simpler than the main alternative metaphysical view of the time, the dualism of Descartes. According to Descartes the world contains both material stuff (tables, chairs, human bodies) and mental stuff (human minds). According to Berkeley, the world contains only mental stuff. So idealism is simpler.
Since Whitehall lies well off the beaten track, and is little advertised, visitors are few and interesting. We averaged a group or two a day, ranging from a Professor of architecture, to three Episcopal ministers from Ohio, to 16 high school students from a summer philosophy program at Brown University. My wife, Shelley Costa, is an 18th-century historian and native of Newport specializing in women's history (Berkeley's wife, Anne, was another fascinating resident of Whitehall) and in the history of mathematics, she was at least as qualified as I was to lead tours of the house, so we shared this duty. Indeed it was Berkeley's interest in mathematics which formed the link to my second main area of research, in the philosophy of mathematics.
I found it a uniquely satisfying experience to spend several weeks living and doing philosophy in a place still so imbued with the spirit of a major figure of the Western philosophical canon. My future ambitions for philosophy-related summer jobs? Most large companies have mission statements, some even have corporate philosophies. So why not "corporate philosopher"? If there isn't such a job, it ought to be invented.
