It’s customary to launch a blog with “Hello, World!”
Hello, I’m George, the Amateur Logician. (See the about page.)
It’s my sincere hope that AmateurLogician.com is intellectually stimulating and enjoyable.
Feel free to contact me to say, “hello.”
If you have suggestions, requests, or find errors let me know.
Genuine philosophy is a spiritual quest for truth, goodness, and beauty.
A desire to know must be grounded in good logic.
From there, the sky is the limit. Please join me in this quest!
Presently, allow me to point out my extensive tutorial on “Trivium Logic.” I may add to it in the future.
The “Propositional Logic” tutorial is in its earlier stages. It’s a work-in-progress, though it already contains the basics.
Subscribe to the Amateur Logician Newsletter here.
We can eventually form some kind of online community.
Also, consider following me on TikTok here and YouTube here. At present there’s some logic and philosophy on my TikTok. The YouTube channel is starting off with some mathematics (basic and advanced), but soon there will be an extensive series on basic propositional and predicate logic.
