Philosophical World Views and Values - Nine Key Perspectives

This course was one of the college's most popular electives when I taught it on campus. Now it's an open-enrollment, online course for learners everywhere!

World Views and Values is an online course that I developed and taught for several years while teaching for a highly ranked college back in New York. Students loved the course, and it became a very popular and highly requested class. As the course developer, I retain all intellectual property rights to the course materials, so I've decided to offer this course (which typically cost students quite a lot to take) to the general public worldwide, at a significant savings.

Through the course of study, students are introduced to a selection of key thinkers, texts, and topics from the history of ideas, centered particularly but not exclusively on Philosophy. Given the theme of the course - World Views and Values - I decided to focus particularly on issues in Ethics, Social Theory, Human Nature, Metaphysics, and Theory of Knowledge. The thinkers and texts discussed here are:

From the Ancient Period:

  • Plato's Republic (selections)
  • Epictetus' Enchiridion and Discourses (selections)

From the Medieval Period:

  • Boethius' Consolation of Philosophy

From the Early Modern Period:

  • Rene Descartes' Discourse on Method
  • Thomas Hobbes' Leviathan (selections)
  • Jean-Jacques Rousseau, Discourse on Inequality
  • Mary Wollstonecraft, Vindication of the Rights of Women (selections)

From the 19th Century:

  • Karl Marx, Alienated Labor and the Communist Manifesto

From the 20th Century:

  • Martin Luther King, I Have a Dream and Letter from a Birmingham Jail

Here's what some of my former students had to say about taking classes with me...

"Dr. Sadler's class was enjoyable and very informative. He offered students excellent resources, e.g. videos, to allow them to excel in his class. His assignments cultivate and improves one's writing and development in a philosophy class. He has enough understanding of the subject to make it so anyone can grasp a concept presented in his class."

"One of the best professors I've ever had...Truly cares about the material and subject he is teaching. I took him for two semesters and did well for both."

"Professor Sadler has the ability to captivate his students by his love for what he teaches. The best part about his class is that he is able to turn tough moral theories into basic models that everyone can understand. It is not the easiest but you will succeed if you do your work...It is a must take class."

"I'm in his class now. It's a great class and I really appreciate all of the extra materials he gives us for resources. My friend had him last semester, and she recommended his class. So far, I'm glad I'm taking it."

"Awesome teacher. Dr. Sadler...wants his students to feel like they are learning something meaningful."

Given that the course is open-enrollment, you can proceed through the material at your own pace. Some learners also find it enjoyable to sign up with a friend. I hope you enjoy the course!

After a successful career as a college professor, researcher, and administrator, I started ReasonIO with my wife and partner, Andi Sciacca to engage in philosophy in public, practical, and professional contexts. I take difficult philosophical texts, thinkers, and topics, and make them accessible for everyday people. That's how philosophy gets traction and remains closely connected with real life!

The work I do with ReasonIO includes online course development and teaching, public speaking, organizational consulting, providing tutorial sessions, development of philosophy content, and philosophical counseling.

I am the Editor of Stoicism Today, a Member of the Center for Contemporary Aristotelian Studies in Ethics and Politics, the producer of the Half Hour Hegel series, and a Team Member with (Slow) Philosophies, I also work with the Institute for Priority Thinking as an executive leadership coach, ethics educator, and curriculum developer.

Although I work in significant part outside of the academy, I remain actively engaged in research and scholarship. To date, I have published one book and dozens of articles and book chapters. In recent years, I have held a Research Residency at the Institute for Saint Anselm Studies, been a Visiting Scholar position at European Graduate School, and was a Charles Chesnutt Library Fellow.
