Philosopher's Way, San Francisco

Philosopher's Way, San Francisco is a 2.7 mi loop trail around the perimeter of John McLaren Park created by artists Peter Richards and Susan Schwartzenberg, staff artists at the Exploratorium. The trail, dedicated on January 5, 2013, is the first and only path built for philosophers in the United States and features fourteen stone markers by mason George Gonzalez intended as "musing stations" to stimulate contemplation. The US$146000 2013 trail was funded as a public art set-aside by the San Francisco Public Utilities Commission, and offers views of Mount Diablo, Mount Tamalpais, Angel Island, and the Pacific Ocean on a clear day.

Design and history
Selected through a competitive process in 2008, Richards and Schwartzenberg were inspired by the philosopher's walks found in other major cities such as Heidelberg, Toronto and Kyoto. According to the artists, “these are places where poets, philosophers and intellectuals strolled through in conversation, considering the ideas of their times.”

The path was laid out by Richards and Schwartzenberg along existing park trails and new trails added by city agencies and volunteers. During their research, the artists noted that regular park users would only stick to a small portion of the park, hampered in part by poor pedestrian access with no contiguous trail. The trails and musing stations were designed to prompt walkers to notice and think about the local landscape and their place within it. Some of the stations provide commentary, while others draw attention to the park's physical attributes. For example, one station features a bench positioned to look out over a meadow to the ocean, and another includes a stone bowl that catches runoff from the surrounding hills. Richards shaped the bowl from a hexagonal column basalt rock taken from Washington state.

Nathaniel Paluga, McLaren Park's self-appointed Resident Philosopher, conducts regular discussion walks on Philosopher's Way, posing philosophical questions.

Musing stations
George Gonzalez created the musing stations from rough-edged Sierra granite, using surplus city curbstones warehoused in nearby Hunters Point. Some of the stations include:
