The "Aliens" are short stories through which attempts are made to approach the paradoxical. For this purpose, and for a more careful philosophical approach, the author takes advantage of literature as an instrument of idea formation, which can surpass scientific language, which struggles to exhaust ways of expression beyond the ordinary reality.

These short stories reveal the intricate puzzles of the human soul, which try to communicate in today's world and which, for the most part, are unable to interpret the parabolic messages and paradoxical events, with their usually inaccurate interpretations.

Man, not humanity, individuals, not the person, are interpretations that can be the subject of paradoxographers. For example, a social analysis is paradoxical, as it has the informational advantage but does not lead to the exit of the social labyrinth.

In the book, the reader will encounter paradoxes, such as pleasure and happiness as emotions of multiple choices are beliefs that do not conform to general acceptance. Or that dreams, while we perceive them with the senses that we trust to distinguish reality from illusion, ultimately require us to recall our trust in unreliable senses. Or the free choice in a society of free circulation of ideas, where "free" choice is directed. Or the paradox of nihilism, where the absence of meaning seems to be a kind of meaning.

All these contradictions to accepted opinion, the author accepts, are not delusions but a daily social practice.
