Mass media do not produce Ideas, but an excess of Information to induce a passivity to interiorize the ruling classes interests as the collective will.
Books were always my preference as a way to find the Truth.
New social media and the blockchain as a more active participatory system will permit the emergence of a myriad of citizens expressing their opinions as it should be in a direct democracy where people are the journalists of Reality.
Most of the people find "the truth" comes from outside, but it comes from inside, from your capacity to be aware of the world injustice.
Injustice just means inequality and that's the meaning of Truth to me.
"Who looks outside, dreams; who looks inside, awakes."
Carl Jung
"What then in the last resort are the truths of mankind? They are the irrefutable errors of mankind."- Friedrich Nietzsche

"The discovery of truth is prevented more effectively, not by the false appearance things present and which mislead into error, not directly by weakness of the reasoning powers, but by preconceived opinion, by prejudice." - Arthur Schopenhauer
