For Taylor, it's literally liquid in a mold. If you're really want context, you can the long poem "God's Determination Touching His Elect." The displacement theory of moral life appears deep in a debate between a Saint and the Soul on "Doubts from the Want of Grace Answered."

Nathan Matias 🦣 @nprofile…d2v0 @nprofile…s45g @nprofile…6r9q Congrats on getting a folding bike! My top tip is to get tires with a very good rolling resistance and puncture resistance, and always bring spare tubes since you can't count on shops to have them (even if you run tubeless). A substantial part of people's belief that folding bikes are slow comes from stock tires that have high rolling resistance. I see people spend so much money on aftermarket lightweight and aero parts for their folding bike, and then use very slow tires. #bikenite npub163cvjt4awndd9szfzzpv8ed720yyx98ee2ua288vpcw3eu57n6rs5tcgde J.

All told, once I add bottles, food, tools, fenders, bicycle bags, locks, rain jacket, and a few other supplies, the whole package is just under 50 pounds. I'm glad the luggage has wheels!

Nathan Matias 🦣 What might it mean to cultivate something that thousands of people collectively decide is worth carrying into the future? This month, I received tenure from Cornell University. The most common question I've been asked is "what will you do with it?" This post, which I outlined before hearing the result, is my answer, in the form of a letter to the public who support my work and who I'm privileged to serve. https://natematias.com/portfolio/2026-06-16-tenure-is-a-promise/ npub163cvjt4awndd9szfzzpv8ed720yyx98ee2ua288vpcw3eu57n6rs5tcgde J.

It seems like every year I have a trip after filing grades, which starts the summer rides in earnest.
