Set of properties chosen under the light of an implicit theoretical paradigmatic justification. Ultimate Reality and Meaning 20 4: This passage suggests that life will be better and better understood as our inquiry delves more and more into the micro- structural levels of living beings. Rather, it is possible to explain the characteristic coexistence of that list of symptoms of life on the grounds of some set of causes.

The problem lies in the disproportionate emphasis on the micro-structure of biological systems, usually in an approach tending to isolate molecular and cellular structures from the organismic and environmental contexts. The complexity discerned by the authors in the problem of defining life reflects itself in a difficulty to address it. The textbooks call attention to the alleged borderline instances between living systems and inanimate matter, in particular, to viruses, understood as exceptions.

We did not find, however, any book that addressed the circular, self-referential organization of living systems by employing the conceptual resources of this theory.

Emmeche observes that definitions of life are seldom discussed in depth or even mentioned in biology textbooks and dictionaries. When the properties listed are interconnected in the context of some paradigm, the list is no longer, as in the case of essentialist definitions, something like a medical syndrome, a collection of symptoms with no underlying cause.

To cast them aside as exceptions seems to be, at first, quite a natural and easy solution. Textbooks that characterized living beings by means of a general description of taxonomic groups highlighting fnudamentos attributes of each group.

Here, it is worth observing that Soares Does the textbook 2: In these sections, the question of the evolution of processes that would make life possible is raised, e.

It is not that there would be any problem in searching for a unity in the diversity of life. Among several misunderstandings and difficulties resulting from this metaphor, we have the problem that it emphasizes a purely informational conception of life.

Textbooks that based its approach to the definition of life on the biological meaning of death. One cannot lose from sight, however, that such a problem is also found in university biology textbooks. The analysis of the textbooks was performed by applying a standard protocol, in order to guarantee a standardized appraisal of how the textbooks dealt with the problem of defining life and life concepts Figure 1.

Remember me on this computer. To put it differently, it is the case of trying to find a list of sufficient and necessary properties for a system to be characterized as living, with no theoretical paradigmatic justification for the choice of properties.

An emphasis on the description of morphological and anatomical features characterizing groups of plants and animals reinforced the search for lists of essential properties. Thus, the characterization of viruses and other structures as borderline cases may be a reflection more of the inadequacy of our defining procedures than of the nature fuundamentos what we are trying to define.

The definition of life proposed includes a set of properties chosen under the light of an implicit theoretical paradigmatic justification, forming a coherent set of interrelated properties. It is important to stress, however, that the claim that the Earth is living strains the ordinary concept of life Bedauand funeamentos a justification through a proper conceptual analysis.


Teoria Neodarwinismo by Dantefgle Fernandes on Prezi

What is the definition of life presented by the textbook, if there is any? At last, all living beings are subjected to death. It can be compared with the memory of a computer and stores thousands of instructions to make cellular proteins.

But a thoughtful analysis can suggest that this solution is not so adequate. As living beings, we have a deep conviction that, in principle, we do know what is life and no remarkable difficulty should appear when we try to distinguish between a living being and something inanimate, or between the living and the dead states of organisms. All the books analyzed put forward some characterization of living beings.

To put it differently, when a definition of life is embedded in a biological paradigm, it is possible to find underlying causes to what previously seemed to be merely a syndrome Bedau Life would appear when an aggregate of molecules, endowed with the ability to perform ordered chemical reactions, extracting from the environment raw materials and energy, managed to maintain its organization and isolate itself from the environment.

Nonetheless, essentialist efforts to define life through lists of necessary and sufficient properties still predominate in the analyzed textbooks.

It is desirable, then, to address this problem in a non-essentialist manner, inasmuch as this is compatible with population thinking. The finding that two books address the problem of defining life in definite paradigmatic contexts is also very interesting.
