Asked what is the disease of our time, the philosopher Emilio Lledó answers the following: "Ignorance, and perhaps also the little reflection and carelessness of language. But above all ignorance and how daring it is. I observe this in certain politicians. It is as if power gave them the School to do and say anything, even without having the slightest idea of what they are doing and saying." The technologies of the Society of knowledge do not invite us to reflect, but to accumulate an excess of data that intoxicate us, thus preventing us from discriminating between what is necessary and what is superfluous. Thoughtful knowledge is replaced by knowledge without thought. We are settling for partial knowledge, detached from an integral wisdom, perhaps because the model proposed to us is not that of the wise and educated man, but that of the expert who is only interested in productive knowledge.

Daniel Innerarity argues that the current society of ignorance stems from the subject of knowledge that subliminally underlies the utopia of the Society of knowledge. "The knowledge through reason, which should provide us with a better and more complete understanding of reality, diminishes. The same technologies that today articulate our world and allow us to accumulate knowledge are turning us into increasingly ignorant individuals."

We must all be aware of when we are speaking out of ignorance. This defect is usually attributed to some "talk show hosts" and to many politicians who talk about everything. In the few cases in which they admit questions from the public, they answer in a categorical tone and almost never reply: "I have to think about this. Tomorrow we will continue talking". That answer, far from subtracting moral authority, grants it. "True wisdom lies in recognizing one's own ignorance." (Socrates).

Why do so many people give their opinions on everything without having a clue? The answer is the 'Dunning-Kruger effect'. These researchers (David and Justin) concluded that "the less we know, the more we think we know". It is a cognitive bias according to which people with less skills and knowledge tend to overestimate those same skills and knowledge. Those who suffer from the 'Dunning-Kruger effect' do not limit themselves to giving an opinion or making suggestions, but try to impose their ideas, as if they were absolute truths, making others look ignorant.

To what extent does an ignorance society currently exist in Spain? According to Eurostat, Spain is one of the three European countries where people read the least and spend the least on books. Javier Marías declared that "in Spain we are living a kind of pride in ignorance". No one is an expert in all subjects at knowledge. We all have shortcomings and ignore many things. Therefore, the best thing to do is to face it with humility and the attitude of an apprentice. The latter is especially applicable to teachers. Teaching implies guiding others in their process staff of learning from the example of the one who teaches. Current pedagogy speaks of the teacher as a learner. Life-long learning is expected of him/her.
