The Ayn Rand Institute has released several videos on YouTube. Recent releases address the topic, “Reasons vs. Faith.”
In one video, a questioner asks, By what standard does one evaluate the concepts of right and wrong in the absence of a supernatural being?
Onkar Ghate answers, “The standard becomes your life and its requirements.” He goes on to explain some of those requirements and why they give rise to the need for morality in the first place. Finally, Ghate criticizes the notion that religion can offer legitimate moral absolutes. He offers the example of God commanding Abraham to kill Isaac. Such morality is actually a sort of “supernatural subjectivism,” akin to personal subjectivism.
Other videos address the Old Testament, the foundations of capitalism, the clash of Western civilization, and other topics, and they are uniformly excellent.
