When a child is in a room about to stick something in the electrical socket, even though its plastic, you still tell them to stay way. You may say something like "boogyman is in there and he will hurt you". You dont have time to explain, and neither does the small child have the ability to understand how electricity works, and that plastic is fine. You just tell them to stay the hell away.

This is a perfect example of the kind of lie that is for the better good.

Most of humanity spends the majority of their time in trivial puruits, uninterested in knowing how the world really works. They have to work 8 hours to earn a living, and spend the rest of their time watching TV, playing video games and things like that. We are infants when it comes to true knowledge. There is a hierarchy when it comes to discovering the most supreme truths of our existence, and only those who swear oaths, who will suffer for truth and are dedicated should be worthy.

The truth is dangerous for those not prepared to comprehend it.

I understand that we dont like being lied to. We insist on the truth, but trust me, the vast majority of mankind are not ready. You have to earn these truths.
