Dr. Sweet,
As you may have noticed, I believe it is important to document that philosophy professors at Texas A&M University are not permitted to teach Plato at their own discretion.
To comply with the new censorship requirements, I have replaced the affected module with lectures on free speech and academic freedom. The censored material is marked in red in the attached document. The required text for the new module is:
Texas A&M, Under New Curriculum Limits, Warns Professor Not to Teach Plato”, The New York Times, January 8, 2026.
