Let me clarify right away that self-development for me is almost identical to experiments and creativity. After all, man as a phenomenon is the most active, tenacious and creative experiment on planet Earth. This superiority, of course, relates to the present moment and does not at all give reason to expect that it will always be so. For example, viruses, as a population, are not inferior to us in biomass, and in the invention of new aggressive forms they periodically pose worthy challenges to us. But still, at the moment, humanity is the most creative and creative form of consciousness known to us. So the speech in the article will not be about vegetarianism at all (or it will be very little about it and not right away). It will be more about the types of people in relation to food and experiments with it. Experiments may be different, and many individuals may not have them at all, so let’s start with the basics of human typology. The leader here is the square typology of Timothy Leary, well described in Leary’s books “History of the Future” and the popularizer of his system, Robert Anton Wilson, “Quantum Psychology” , as well as in Timothy Leary’s Harvard questionnaire “Social Perception Test”. The criteria highlighted by Leary are ingenious and simple. The first division is into people for whom “the world is friendly” and “the world is hostile.” Those who from infancy perceive the world as friendly are quite relaxed, confident, and trust people and the world as a whole. The living and non-living mother around them is so safe in their minds that they are ready to taste it, or “experience the world through their mouth.” These people have known since childhood not only the taste of milk and semolina porridge, but also sand, maple leaves, and, alas, cloves in the cold. They happily slobber on a blade of grass, stick it in an anthill and then lick it. The second half of the homo sapiens types perceive the world as a whole as not the safest place. These individuals have increased anxiety, they are vigilant, 24 hours a day, at the edge of their consciousness (and vision too) they expect a trick (even the most confident and active of them). As children, these people take food only from their mother’s hands, and even then with suspicion, because who in this world can you trust? Such people are conservative in food all their lives, picky, and often become... well, more on that later. Let's depict the data of the group in Table 1: The world is hostile The world is friendly Anxious, suspicious, restless, conservative, cautious. Calm, relaxed, trusting, experimenters, liberals.
