對你來說是真的才是真的?

真相是，「對你來說是真的才是真的」在山達基十分流行，可惜不是羅恩賀伯特說的。

普羅泰戈拉：真相是相對的。它只是意見。

蘇格拉底：你的意思是，真相只是主觀意見？

普羅泰戈拉：正是。對你來說是真的才是真的，對我來說是真的才是真的。真相是主觀的。


蘇格拉底：這真是你的意思？我的意見是真相，由於它是我的意見？

普羅泰戈拉：確實是。

蘇格拉底：我的意見是：真相是絕對的，不是意見，而你，普羅泰戈拉先生，是絕對錯的。既然這是我的意見，根據你的哲學，你必得接納它是真的。

普羅泰戈拉：蘇格拉底，你是十分正確的。

羅恩賀伯特說的，我找到最相近的是「你自己觀察到才是真的。」(What is true for you is what you have observed yourself.) 作用是一樣的。用來推銷課程：要你親身觀察效果，安慰劑也總會有效的，抽獎總有人中的，有效便多了一個堅定信徒，錢是一樣收了。用來掩飾真相：你每日見到的山達基人，犯了什麼罪？全世界報紙和法庭的紀錄全是有人在背後搞鬼的。

Protagoras: Truth is relative. It is only a matter of opinion.

Socrates: You mean that truth is mere subjective opinion?

Protagoras: Exactly. What is true for you is true for you, and what is true for me, is true for me. Truth is subjective.

Socrates: Do you really mean that? That my opinion is true by virtue of its being my opinion?

Protagoras: Indeed I do.

Scorates: My opinion is: Truth is absolute, not opinion, and that you, Mr. Protagoras, are absolutely in error. Since this is my opinion, then you must grant that it is true according to your philosophy.

Protagoras: You are quite correct, Socrates.
