This offering is an enhanced and updated version of Introduction to Philosophy Copyright © by Lumen Learning licensed under a Creative Commons Attribution 4.0 International License, except where otherwise noted. These enhancements and updates have been made:

• Small content upgrades, modifications and additions are incorporated to enrich the learning experience in Units 1, 5,  6 and 8. These updates reflect course content currently in use for PHI101 Online at Pima Community College for  Fall  2024.
• Quoted excerpts from philosophical works are indented and italicized to allow learners to distinguish this material from the standard textual content.
• Formal course assessments and references to tests are removed, though use of assessments is encouraged and expected with use in a formal classroom setting.
• Interactive (H5P) exercises labeled Check Your Understanding are added to each section to help learners review selected key concepts.
• Questions and “thought projects” labeled Apply Your Understanding are included in some sections to inspire reflection on and awareness of connections between philosophical concepts and present-day situations.
• All videos have been embedded in the content instead of accessed by links.  Some new videos are added and some videos formerly used as “Supplementary Resources” are relocated in the main (assigned) content.
• The Course Introduction is provided as Front Matter; it is moved from the Unit 1 content, and the intended Unit 1 Overview is restored.
• A Glossary of Key Terms is accessible as course Back Matter.
