Who to Watch on YouTube: Joe Folley’s Unsolicited Advice and the Seven Levels of Logic
August 2026
As part of my series on interesting and worthwhile YouTube creators, one channel worth watching is Unsolicited Advice, created by Joe Folley. It is a rare example of a channel built around philosophy, logic, and serious intellectual questions that has managed to find a large modern audience.
The channel was created in January 2023 and has grown remarkably quickly. As of 2026, public channel tracking sites estimate that Unsolicited Advice has approximately:
- 950,000+ subscribers
- 67–68 million total views
- Around 260–270 videos
For a philosophy and education channel, those numbers are impressive. It demonstrates that there is still a significant audience for long-form ideas when they are presented clearly and accessibly.
Joe Folley’s background adds credibility to the channel. He studied philosophy at Cambridge University, with particular interest in logic, and his videos often combine academic knowledge with a conversational style. Instead of presenting philosophy as something locked away in universities, he approaches it as something connected to ordinary life: how we think, argue, believe, and understand the world.
One of his videos, “The 7 Levels of Logic,” is a good example of what makes the channel interesting.
The video presents logic as a progression from everyday reasoning to professional research.
The first level is Pre-Logic. This is where most people operate: they have an instinctive sense that some arguments seem convincing and others do not, but they lack a formal framework for explaining why.
The second level is the Fallacy-Monger. At this stage, people learn to identify common mistakes in reasoning, such as ad hominem attacks, appeals to authority, and other informal fallacies. This is a useful beginning, but logic is much deeper than simply spotting mistakes in arguments.
The third level is Basic Formal Logic. Here reasoning becomes mathematical. Propositional logic introduces symbols, truth tables, and logical connectives such as “and,” “or,” and “if-then.” Arguments can now be tested with precision rather than intuition.
The fourth level is First-Order Logic and Friends. This expands logic into more complex statements involving concepts like “for all” and “there exists,” along with connections to mathematics, sets, and probability.
The fifth level moves into Specialized Logical Systems. This includes areas such as modal logic, which studies necessity and possibility; epistemic logic, which examines knowledge and belief; and formal semantics, which explores meaning in language.
The sixth level is Metamathematics and Metalogic: logic studying itself. This includes questions about consistency, completeness, and Gödel’s famous incompleteness theorems, which showed that even powerful mathematical systems have limits.
The seventh level is Current Logic Research. At this stage, logic becomes an active professional field connected with mathematics, computer science, artificial intelligence, linguistics, and philosophy.
What makes this video interesting personally is that I am familiar with six of the seven levels. That does not mean I am an expert in them. Far from it. Some areas are much more familiar than others, and like many people who have studied these subjects, I am also a bit rusty. Knowing about modal logic or Gödel’s theorems is very different from actively working in those fields.
That is also one of the strengths of Joe Folley’s presentation. It reminds viewers that there is a difference between recognizing a subject, understanding its basic structure, and mastering it professionally. Logic is not just a collection of tricks for winning arguments online. It is a centuries-long discipline that has shaped mathematics, philosophy, computer science, and our understanding of reasoning itself.
The appeal of Unsolicited Advice is that it makes these enormous subjects approachable. It invites viewers to move beyond simple opinions and explore the deeper machinery behind human thought.
For anyone interested in philosophy, critical thinking, artificial intelligence, mathematics, or simply understanding how people reason, Joe Folley’s channel is worth watching.
