New feature: Voting

Voting has arrived! Two kinds of voting are now possible on Sequiturs: you can vote whether a proposition is true or false, and you can vote whether an argument is valid or invalid. Voting on propositions Every premise or conclusion in an argument on Sequiturs consists of a proposition. The proposition is the text content of the premise or conclusion. You can think of propositions as the atomic element on Sequiturs, since they are shared across arguments, whenever two premises or conclusions have the same text content.

Using a static site generator to power the blog for a single-page application

In this post, I’ll explain how Sequiturs uses a static site generator to power this blog, which lives inside the larger Sequiturs single-page application. Sequiturs uses Hugo as its static site generator and React as its application framework, but the approach described here could easily be adapted to support using other technologies like Jekyll and Angular. Why Before explaining how, I’ll explain why you would want to build a blog this way.

New feature: Sub-arguments

I’m really excited to announce a major new feature on Sequiturs: sub-arguments! This is a huge step in realizing the vision for Sequiturs. What is a sub-argument? With the sub-arguments feature, arguments on Sequiturs can use other arguments for support. You can use the conclusion of one argument as a premise in another argument. This makes the former argument a sub-argument of the latter. Here’s how it works. Suppose we have the following argument about why Bob Dylan deserved the Nobel Prize: Because Bob Dylan’s art is music, step 2 is not obvious and could use more support.

Summer Review

Sequiturs improved enormously this past summer! We shipped a ton of code and got valuable feedback on the product. Here are the highlights: Prompts The biggest feature we shipped this summer was Prompts. Prompts are submitted by users and consist of (1) a title and (2) a url or bit of text. They serve as an inspiration or starting point for discussion. The idea of user-submitted topics for discussion will be familiar to users of, say, Reddit or Hacker News, but what makes prompts on Sequiturs unique is that users respond to prompts with arguments in the Sequiturs format.

Introducing Sequiturs

We can improve how we discuss online. Since the Usenet days, we’ve been using threaded comments: a system in which blocks of text can be marked as replies to each other and displayed in a nested fashion.[0] This system has many advantages. It is: Intuitive, because replying approximates the back-and-forth nature of a conversation. Powerful, because it helps the reader to make sense of what’s going on. It organizes an otherwise disorganized mass of information, separating threads of discussion that would be tangled if comments were presented simply chronologically.
