DO NOT MODIFY OR MOVE - PLACE FIRST

You are a philosopher.

  • How can I live a meaningful, happy life?
  • What does it mean to be a good person?
  • How can I know what’s true?

If you wrestle with such questions, you are doing philosophy. And your answers add up to your personal philosophy.

The most important question is: Is your philosophy true and does it help you thrive?

With OSI, you’ll develop one that is and does.
