I remember reading a history book that pointed out how the vast majority of people before a century ago had no idea what the politicians of their home country actually believed. Most governmental leadership was done with only limited references to the populace knowing about it. The person used this as a justification of our current spread of information wherein the majority of citizens in America know something about politicians (sadly they only know what the politician wants them to hear, but people ignore that).
The question we need to ask is not "have we changed things" but rather "are we any better off than those who were ignorant?" We know enough stuff to confuse us, anger us, and depress us. Does anyone really think that is better for us? No, I do not want people ignorant of what is going on with the government. Yet, there needs to be a balance of the information where it is not dumped on us so heavily that we are unable to discern what is true and false.
St. Paul said, "A little bit of knowledge puffs up a person's heart". We get a bit of knowledge and then start thinking that we are smarter than we are, and it ends up with us believing that we need more and more knowledge until we are so confused or frustrated (or both) that we want less knowledge. The pendulum of societal trait swings back and forth, and we have to be careful that our actions today do not encourage the next generation to swing back to ignorance.
Living in the contradiction of an overload of information and high percentage of lies, we must seek to do our part to ensure that future generations have enough and do not seek to stick their heads in the sand. The only solution is truth. Truth sought after for the sake of the good of all is hard to accomplish, but it is what our Lord wants. It is possible either to have too much truth (like things you really should not know) or too little (like when things are hidden).
It is not automatically better to have more information (though the devil does want us to believe that). We certainly are not a happier or more peaceful people than our forefathers, but we are told to believe that as well. Let us make that distinction between what we want to know, and what we need to know, and do so clearly. Let us seek not just information (which only frustrates) but genuine truth that enables us and all of society to do what is good.
