Francis Hutcheson (1694-1746) was a pivotal early figure of the Scottish Enlightenment, a movement which strongly embraced empiricism and concentrated on the study of human nature and the relationship of individuals and society. Born in Ireland to a line of Scottish Presbyterian ministers, Hutcheson was educated by dissenting Irish Presbyterians in Ulster before matriculating at the University of Glasgow, where he studied philosophy and theology. In 1719 he was licensed to preach in Ireland, but rather than adopting the more traditional views of his forefathers, he gravitated toward the tolerant and liberal “New Light” Presbyterianism. Instead of further pursuing the ministry for which he had trained, he put his efforts into founding a dissenting academy in Dublin—a successful venture that occupied him for the next ten years. While teaching in Dublin, he moved in intellectual circles, and it was there that he wrote the four early treatises—collected into two books, the *Inquiry* of 1725 and the *Essay* of 1728—that quickly established his reputation as a philosopher. On being appointed chair of moral philosophy at his alma mater, he left Ireland for Glasgow in 1729. Contemporaries described Hutcheson as a popular and animated professor—the first at Glasgow to deliver lectures in English rather than exclusively in Latin. His most famous student was Adam Smith (enrolled 1737-40). Hutcheson's influence on Scottish thinkers was considerable. With his emphasis on the primacy of feeling over reason in our moral perceptions, he inspired David Hume’s moral sentimentalism. His analysis of natural rights and property in the *Inquiry* (Treat. II Sect. VII) as well as in his later works directly influenced Smith. The Scottish school of common sense realism derived partly from Hutcheson's explication of moral sense theory. His influence also made its way to colonial America, where his works were included in college curricula beginning in the mid-1700s. John Adams and other signers of the Declaration of Independence are known to have read Hutcheson. In the *Inquiry*, he takes up Locke’s epistemology of sense perception and broadens it into a theory of the “internal senses”—faculties of perception as powerful as the commonly designated five external senses. Elaborating Lord Shaftesbury’s notion of a “moral sense” and the earl's analogy between beauty and virtue, Hutcheson divided his *Inquiry* into a discussion of the sense of beauty and of the paramount moral sense—both being internal senses which operate without depending on mediation by the will or reason. Like Shaftesbury and the philosopher Richard Cumberland, Hutcheson held a strong distaste for the Hobbesian worldview. In the vein of the former two, he promoted a vision of humans as naturally benevolent and innately interested in the welfare of others, maintaining that others’ good brings us no less pleasure than our own good. Notably, he also sowed the seeds of utilitarian thought with his phrase “the greatest happiness for the greatest numbers” (Treat. II Sect. III). **Main Reading** The reading below is available at the Online Library of Liberty: * The [Inquiry](https://oll.libertyfund.org/titles/leidhold-an-inquiry-into-the-original-of-our-ideas-of-beauty-and-virtue-1726-2004), comprising the first two of Hutcheson's four early treatises (we are reading the 1726, or 2nd edition, of the book): read the [Preface](https://oll.libertyfund.org/titles/leidhold-an-inquiry-into-the-original-of-our-ideas-of-beauty-and-virtue-1726-2004#lf1458_head_019) and Treat.

This Saturday lets run to the National Mall! We will start at Roosevelt Island at the crosswalk in the center of parking lot. (Note there is an alternative meeting spot, it is right on the Custis trail, on the North side of Gateway Park, near Langston Blvd and Lynn St; it will be clearly marked as the meeting spot if conditions are bad on a given Saturday. Ignore this unless told otherwise. Afterwards stay for coffee, we'll wander up to Rosslyn and either meet in Compass or, if the weather is nice enough, at the Plaza opposite the Metro. Note: Photos taken during the event may end up on Instagram, Meetup, Strava and similar platforms. \|LOCATION: Roosevelt Island Parking Lot. Use this map to locate the parking lot ([https://www.google.com/maps/place/38%C2%B053'48.2%22N+77%C2%B004'02.1%22W](https://www.google.com/maps/place/38%C2%B053'48.2%22N+77%C2%B004'02.1%22W)) [GPS: 38°53'51.99"N 77° 4'3.24"W]. To help new people find the group, please meet in the middle of the parking lot. Please meet 10 min. before the start time.

We'll be doing an out and back route, so everyone will just turn around at the halfway time marker. We generally average from 8-12 min/miles and run for fifty minutes. But, you can run any amount of time or mileage. And if you need to walk, it's not a problem either, everyone needs to start somewhere! ROUTE: The usual route is [https://onthegomap.com/s/7r0gvj5r](https://onthegomap.com/s/7r0gvj5r). It may vary occasionally. The full circuit works out to around 8:30 min/mile for a 50 minute run. Slower paces can turn around earlier, faster paces can run farther. PARKING: Use this map ([http://bit.ly/i2dWD0](http://bit.ly/i2dWD0)) to find parking in Rosslyn. There are parking lots at Roosevelt Island and above the Continental Lounge. There are also meters and pay garages. DIRECTIONS: For those of you driving to Roosevelt Island, please note that the parking lot is only accessible from the NORTHBOUND lane of GW parkway. You will see it right after the Roosevelt Bridge. Also whenever it is warmer the parking lot fills up really quickly. You are strongly advised to use alternative travel or park in Rosslyn. They do ticket illegally parked cars at the island!! METRO: Orange or blue to Rosslyn. From N. Moore St, turn left; right onto 19th St; cross Lynn St. and turn left; take the trail on the right just before the Key Bridge.

https://ridewithgps.com/routes/54635719 20.6 miles; mostly paved trail; some designated bike lanes and relatively calm neighborhood streets. Toilet facilities at beginning and middle of the ride. Lunch at Fletcher's Cove, 13 miles into the ride. On this ride we explore two local gems: Rock Creek Trail/Beach Drive and the Capital Crescent Trail. Rock Creek Park is a national treasure and affords magnificent nature views. We'll ride on the trail and on sections of Beach Drive that have been closed to motor vehicle traffic. Feel free to stop for photos at Peirce Mill and the adjacent waterfall. We continue south past the National Zoo on the Zoo Loop and down into Georgetown. At the Georgetown waterfront, we'll make an optional stop at mile 0 of the C&O Canal. You may also choose to stop and explore the Georgetown Waterfront Park and its terrific views of the Potomac. From Georgetown we go west on the Capital Crescent Trail. After our lunch stop at Fletcher's Cove, we head further north to Bethesda then east through well-sculpted Chevy Chase neighborhoods before finishing the ride. **Please charge your battery, pump your tires, and check your brakes. Consider packing a spare tire tube. The ride is on paved trail and asphalt roads, but there are a few hilly segments. As usual, analog bike riders are most welcome.** **We highly recommend that you download the Ride With GPS route map.** https://ridewithgps.com/routes/54635719 **About Peirce Mill** Peirce Mill was built on Rock Creek in 1829 at the behest of Isaac Peirce. Using the moving water as a power source, the mill ground corn, wheat, and rye. Succeeding generations further developed the mill, sawmill, orchard, and tree nursery. In 1890, an act of Congress incorporated the mill and 350 acres of the property into Rock Creek Park. **About Fletcher's Cove** Fletcher's Cove, called by many customers "Fletcher's Boathouse," has been in this location since the 1850s and is renowned as a fishing and recreational area. The nearby Abner Cloud House is the oldest building on the canal, dating back to 1802. After 145 years of business, the fourth generation of the Fletcher family retired in 2004, and a National Park Service concessionaire assumed responsibility for the operation of the boat rental and fishing tackle/bait operation. The area surrounding the boathouse was then officially named Fletcher's Cove, though most people still call it Fletcher's Boat House. **About the C&O Canal** The Chesapeake and Ohio Canal operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains. The canal’s roots begin with George Washington’s dream of a waterway trade route. 74 locks were built. The full canal towpath is 184 miles long. See our September calendar for 4-day adventure on the towpath. **About the Capital Crescent Trail** The Capital Crescent Trail follows an abandoned Georgetown Branch railroad right of way and extends 11 miles from Georgetown, in the District of Columbia, to Bethesda, MD. It will eventually link to Silver Spring. The trail, one of 500 rail-to-trail projects in the nation, traverses’ park land and neighborhoods and includes stretches along the Potomac River. We'll cross a railroad trestle at Arizona Avenue and ride through the Dalecarlia Tunnel near the DC/MD border. **Free Ride With GPS for E-Bike Lovers** The Ride With GPS E-bike Lovers club membership is now free as [www.ebikelovers.com](http://www.ebikelovers.com/) generates sufficient income from ads to cover the costs.

**This talk has completely sold out in advance and no additional tickets will be sold at the door. A repeat of the talk at Penn Social in DC on Monday, May 18 still has tickets available.** [Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“How AI Alters Thinking,”** on dealing with artificial intelligence’s capacity to change and undermine our thought processes, with Eli Alshanetsky, assistant professor of philosophy at Temple University, principal investigator at its Cognitive Integrity Lab, and author of an upcoming book on AI and freedom of thought. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-how-ai-alters](https://events.ticketleap.com/tickets/profsandpints/nv-how-ai-alters) .] Doctors who give bad advice can be sued for malpractice. Teachers belong to a profession with set standards. When artificial intelligence guides you, however, that guidance comes with a disclaimer: Use at your own risk. Every day millions of people take that risk, and usually AI seems genuinely helpful. But even if AI gives us good answers, might its use over time do bad things to how we think? Explore the relationship between AI and our own minds with Eli Alshanetsky, whose Cognitive Integrity Lab studies how artificial intelligence changes how we think, learn, and build trust. Author of *Articulating a Thought* and the upcoming book F*reedom of Thought in the Age of AI*, he’s on the cutting edge of efforts to answer AI-related questions such as: How can we tell when work is truly our own? How can technology support rather than replace authorship and reflection? What does trust mean when AI mediates our relationships with others and with our own thoughts? To set up his discussion of potential consequences of AI, he’ll describe how social media’s impact on society serves as a preview. Social media didn’t just give people what they wanted to click on, it actually changed what they regarded as click-worthy. It broke attention spans and fueled radicalization across millions of very different people. It left us with people who doom-scroll for hours, who can’t focus, who don’t know what to trust anymore. If you’d shown people this version of themselves ten years ago, would they have chosen it? Artificial intelligence is making a similar deal with us, but the stakes are higher. It isn’t chasing clicks. It’s optimized for giving you the most satisfying response to whatever is on your mind right now. The risk over time isn’t just that you’ll get lazy. More profoundly, even when you think hard, your sense of what counts as good thinking—as well as what sounds like you—will shift to match what AI has been feeding you. We’ll consider what kind of person this produces and whether this is someone we want to be or want children to become. Professor Alshanetsky will lay out a practical framework, which he calls “the interaction layer,” for using AI without letting it replace the thinking it’s supposed to support. He’ll also talk about what AI-related concerns should be the focus of parents and educators. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Join me and our member Yazmin M for a Sunday afternoon hike at Windy Run Park in Arlington! Getting to the waterfall at Windy Run is a fun little adventure right in Arlington! Most of the walk through the woods is nice and easy, but we will hop on some rocks to cross a couple of streams and go down a set of steep steps alongside the 35 foot waterfall. Yazmin says: I usually take my time going down as my left knee can be achy at times :) The hike should take about one hour and fifteen minutes. Wear shoes with good grip, and bring a water bottle, and mosquito repellent. We will meet by the park entrance on N Kenmore street. Yazmin recommends you park on the cul-de-sac around 2455 N Kenmore St, Arlington, VA 22207. Let us know if anyone needs a ride from Metro, we'd be happy to help with carpooling. Hope to see you!

Join us for brunch and Freethinker discussion! We will meet at Caboose Commons at 11am (in the upstairs area of the building) to munch and chat. We'll organize into a handful of separate tables with 6-8 people at each table. Each person will write down ideas, drop 'em in a hat, and each group will pick 'em out at random to determine our topic(s). We'd love to mix the "louder" and "quieter" voices so that everyone has a chance to weigh in—we want to hear all perspectives! :) We're a very friendly bunch, and welcome participation from newbies and old-bies alike! Come with your best ideas—anything goes. Feel free to post interesting articles, videos or thoughts in the comments section beforehand to inspire our discussion. PLEASE NOTE: We have placed a cap on the event, so if your plans change, please adjust your RSVP, so someone on the Wait List can attend.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The Physics of Baseball,”** with Scott Paulson, professor of physics and interdisciplinary liberal studies at James Madison University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-physics-of-baseball](https://events.ticketleap.com/tickets/profsandpints/nv-physics-of-baseball) .] Profs and Pints is offering baseball fans an even bigger treat than Cracker Jack, an exploration of the physics underlying their beloved sport. Professor Scott Paulson, who regularly teaches introductory physics classes that make the physics behind real-world phenomena accessible to all, will discuss the forces and phenomena that come into play in baseball during pitching, batting, and fielding. He’ll toss you basic physics concepts that help explain how baseball’s routine plays got to be that way, and he’ll explain what’s going on in some situations where the laws of physics seem to be violated by what’s happening on the field. Ever wondered why curveballs curve or knuckleballs behave so strangely? You’ll learn how Newton’s laws and the Magnus force explain how pitchers get drastically different results from subtle differences in their releases. Curious about what exactly the “sweet spot” of the bat is? Ever wondered how big an advantage batters get from the thin air of Mile High Stadium? We’ll explore the physics of the batted ball, examining the phenomena of waves and analyzing the interaction of ball, bat and batter with the help of high-speed video. During one of the more exciting scenarios in a baseball game—the close play at the plate—fans often see outfielders throw to an infielder rather than directly to home. We’ll look at the pros and cons of this relay play, known as a “cut-off,” in the context of the physics of projectile motion. Finally, we will also look into high-profile cheating scandals involving corked bats and doctored balls. Dr. Paulson will present models to explain how these alterations to the equipment can benefit the batter and pitcher respectively, and he’ll discuss how much these models are backed up by data. These few hours in a brewpub will forever enhance your enjoyment of time at the ballpark. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)
