Before returning to what is the human essence, we see again the answer to the question: what is the essence?. The answer can be articulated in two ways:
a) The essence is the essence of the substance.
b) The essence is the ultimate answer to the question: what is something or someone. "
The two answers are exhausted itself, provided we are familiar with metaphysical concepts, provided we know what is the substance, or what is something or someone. The "profane" can say that it is impossible or useless to ask those things, that each reality is one way and there is no definitive answer to these questions, we then face a relativist denies that there is truth in this case all we can try is to make him see that falls into a contradiction, since for him it is true that it is useless to ask those things, then for it, yes there is the truth about something. We can also remind you if the day before it was ever the question "What is this, or what am I?. If you
has no concept of substance, you know, we can say that the substance is the intrinsic cause of the existence of beings, for example, the soul is the substance of living beings, for it is said that the soul is the substantial form the body.
The form is something intangible that is not done, what is done is to bring the form with matter, for example, a carpenter does not make a chair, has inside, he takes the field, in this case wood and you gives the chair form, and we have a chair that is the meeting as chair with the wood material.
In the case of living things, "profane" say that there is no soul, and if asked by the intrinsic cause of a living being, possibly answer genes, this is a widespread misconception, some more "insiders" say that the soul is the genetic development program is something intangible, and thus believe save the furniture, but this does not correspond with reality, and if no, do the test, ask him or ask you with my eyes closed: Did you ever in your life have you seen your mother as a handful of genes?, have you ever love a genome, when a child ever months smiling in your arms, you thought it was something like a robot that was within a few genes or a program that was what made him smile?.

Aristotle says that essence is what goes into the definition. For him, the man is a rational animal, and if the "secular" think that living things have no soul, think a little about what is meant by the word animal, animated, endowed with a soul, which is in itself the beginning of his movement.
The critical issue that separates man from other animals, is to be rational. When we try to say what is an animal, we begin by saying which is a feline, a canine, a ruminant, a beetle, etc ... and then a little more nuanced, but the very definition, limited to a lifestyle, a certain environment. With man, the definition speaks of its rationality, it is his understanding, his freedom and his will which makes it free from environmental constraints. These features are characteristic sound of the man of spiritual beings who have no body, in our case only, we are an embodied spirit, a spirit of a rational soul and body.
Aristotle died BC, did not know him. Jesus Christ showed us the true potential of understanding, freedom and human will hurt by the original sin. We who have known each other and we know that Jesus Christ is alive, we can say that the essence of man is being created in the image and likeness of God to Amar. And so and for that we are body, see, dream, think, speak, cry, pray, live and die.
