I really don't get what you're trying to say. How exactly does someone 'seek the truth in things'?
That´s a kind of art everyone must learn within our lives, but it´s nothing that´s taught in school. If it was, that woud be easy. You can learn various subjects in school, but this.. general wisdom or how to call it, cannot be learned, it can only be learned by experience, observation, comparing, thinking a lot about things.. the better you´re at it, the easier it is to distinguish good from bad, true from false or the subtleties and variations in between..
For example, why there were masses of people following false gurus like Osho, or Hitler. Because their teaching SEEMED to be great on the surface. So they get hooked to it uncritically, become blind followers and believe every single thing they say. But we need to question everything, all the time. That´s what many people fail to do. It´s very well described in the book The Road Less Travelled, which I always recommend because it´s one of the greatest books I ever read.
People who are not very good at critical thinking are then often harmful not only to themselves because they become victims of their own ignorance by falling for fake teachnigs or scams, but what´s worse they are often unfair to others, because they don´t get them, or understand them wrongly or twist the trust terribly.
