II. Read the following text paying attention to the highlighted words. Explain or interpret the contextual meaning of the underlined phrases

Biology is the science of life. The term biology was introduced in Germany in 1800 and popularized by the French naturalist Jean-Baptiste de Lamarck as a means of encompassing the growing number of disciplines involved with the study of living forms. The scope of biological science is so broad that it has been subdivided into separate branches for convenience of study. Despite apparent differences, all the subdivisions are interrelated by basic principles that underlie all biological manifestations.

It was once the custom to separate the study of plants (botany) from that of animals (zoology), and the study of the structure of organisms (morphology) from that of function (physiology). The English zoologist Thomas Henry Huxley was the first to insist that the conventional segregation of zoology and botany was intellectually meaningless and that all living things should be studied in an integrated way. Huxley’s approach to the study of biology is even more cogent today, because scientists now realize that many lower organisms are neither plants nor animals. The limits of the science, however, have always been difficult to determine, and as the scope of biology has shifted over the years, its subject areas have been changed and reorganized.

The current approach to the study of living things is based on the levels of biological organization involved — whether molecules, cells, individuals, or populations — and on the specific subject matter under investigation—for example, structure and function, types and classification, and growth and development.

Molecular biology, which spans biophysics and biochemistry, has made the most fundamental contributions to modern biology. Much is now known about the structure and action of nucleic acids and protein, the key molecules of all living matter. The discovery of the mechanism of heredity was a major breakthrough in modern science. Another important advance was in understanding how molecules conduct metabolism, that is, how they process the energy needed to sustain life.

Cellular biology is closely linked with molecular biology. To understand the functions of the cell — the basic structural unit of living matter — cell biologists study its components on the molecular level. Organismal biology, in turn, is related to cellular biology, because the life functions of multicellular organisms are governed by the activities and interactions of their cellular components. The study of organisms includes their growth and development (developmental biology) and how they function (physiology). Particularly important are investigations of the brain and nervous system (neurophysiology) and animal behaviour (ethology).

Population biology became firmly established as a major subdivision of biological studies in the 1970s. Central to this field is evolutionary biology, in which the contributions of Charles Darwin have been fully appreciated after a long period of neglect. Population genetics, the study of gene changes in populations, and ecology, the study of populations in their natural habitats, have been established subject areas since the 1930s. These two fields were combined in the 1960s to form a rapidly developing new discipline often called, simply, population biology. Closely associated is a new development in animal-behaviour studies called sociobiology, which focuses on the genetic contribution to social interactions among animal populations.

Biology also includes the study of humans at the molecular, cellular, and organismal levels. If the focus of investigation is the application of biological knowledge to human health, the study is often termed biomedicine. Human populations are by convention not considered within the province of biology; instead, they are the subject of anthropology and the various social sciences. The boundaries and subdivisions of biology, however, are as fluid today as they have always been, and further shifts may be expected.

V. Read the extracts from the Pope John Paul II’s message to the Pontifical Academy of Sciences on evolution and the origin of life. Consider and discuss the questions following the text in the Discussion section

In celebrating the 60th anniversary of the Academy’s refoundation, I would like to recall the intentions of my predecessor Pius XI, who wished to surround himself with a select group of scholars, relying on them to inform the Holy See in complete freedom about developments in scientific research, and thereby to assist him in his reflections.

He asked those whom he called the Church’s Senatus Scientificus to serve the truth. I again extend this same invitation to you today, certain that we will be able to profit from the fruitfulness of a truthful dialogue between the Church and science…

I am pleased with the first theme you have chosen, that of the origins of life and evolution, an essential subject that deeply interests the Church, since Revelation, for its part, contains teaching concerning the nature and origins of man. How do the conclusions reached by the various scientific disciplines coincide with those contained in the message of the Revelation? And if, at first sight, there are apparent contradictions, in what direction do we look for their solution? We know, in fact, that truth cannot contradict truth… It is necessary to determine the proper sense of Scripture, while avoiding any unwarranted interpretations that make it say what it doesn’t intend to say. In order to delineate the field of their own study, the exegete and the theologian must keep informed about the results achieved by the natural science…

…The Encyclical Humani generis (1950), considered the doctrine of “evolutionism” a serious hypothesis, worthy of investigation and in-depth study equal to that of the opposing hypothesis… Today, new knowledge has led to the recognition that the theory of evolution is more than a hypothesis…

…The Church’s Magisterium is directly concerned with the question of evolution, for it involves the conception of man: Revelation teaches us that he was created in the image and likeness of God…this doctrine…is pivotal to Christian thought… St. Thomas observes that man’s likeness to God resides especially in his speculative intellect, for his relationship with the object of his knowledge resembles God’s relationship with what he has created. But even more, man is called to enter into a relationship of knowledge and love with God himself, a relationship which will find its complete fulfillment beyond time, in eternity. All the depth and grandeur of his vocation are revealed to us in the mystery of the risen Christ. It is by virtue of his spiritual soul that the whole person possesses such a dignity even in his body. Pius XII stressed this essential point: if the human body takes its origin from pre-existent living matter, the spiritual soul is immediately crated by God…

It is significant that in St. John’s Gospel life refers to the divine light which Christ communicated to us. We are called to enter into eternal life, that is to say, into the eternity of the divine beatitude.

To warn us against the serious temptations threatening us, our Lord quotes the great saying of Deuteronomy: “Man shall not live by bread alone, but by every word that proceeds from the mouth of God.”

Even more, “life” is one of the most beautiful titles which the Bible attributes to God. He is the living God.

I cordially invoke an abundance of divine blessings upon you and upon all who are close to you.


1. How does the Pope interpret the notion of “life” in the message?

2. Prove the authors opinion concerning the importance of cooperation between theology and natural sciences.

3. Why is the problem of the origin of man of extreme importance for the Church?

4. Do any obvious contradictions between the theological and scientific points of view on this problem exist? Is it possible to overcome them?

5. How does St. Thomas regard the nature of man?

6. Explain the meaning of the phrase “truth cannot contradict truth”.

7. Do you agree with the Church’s official position concerning the origin of life and man expressed in the Pope’s message?

V. Read the following texts on animal rights. One of the texts is an article from the official website of an American animal protection organization called PETA (People for the Ethical Treatment of Animals), the other is an extract from a summary on cruelty to animals from the free encyclopaedia Wikipedia. Answer the questions in the Discussion section


Almost all of us grew up eating meat, wearing leather, and going to circuses and zoos. Many of us bought our beloved “pets” at pet shops, had guinea pigs, and kept beautiful birds in cages. We wore wool and silk, ate McDonald’s burgers, and fished. We never considered the impact of these actions on the animals involved. For whatever reason, you are now asking the question: Why should animals have rights?

Australian philosopher, Princeton professor, and author of numerous ground-breaking books — including 1975’s Animal Liberation, Peter Singer states that the basic principle of equality does not require equal or identical treatment; it requires equal consideration. This is an important distinction when talking about animal rights. People often ask if animals should have rights, and quite simply, the answer is “Yes!” Animals surely deserve to live their lives free from suffering and exploitation. Jeremy Bentham, the founder of the reforming utilitarian school of moral philosophy, stated that when deciding on a being’s rights, “The question is not ‘Can they reason?’ nor ‘Can they talk?’ but ‘Can they suffer?’” In that passage, Bentham points to the capacity for suffering as the vital characteristic that gives a being the right to equal consideration. The capacity for suffering is not just another characteristic like the capacity for language or higher mathematics. All animals have the ability to suffer in the same way and to the same degree that humans do. They feel pain, pleasure, fear, frustration, loneliness, and motherly love. Whenever we consider doing something that would interfere with their needs, we are morally obligated to take them into account.

Supporters of animal rights believe that animals have an inherent worth — a value completely separate from their usefulness to humans. We believe that every creature with a will to live has a right to live free from pain and suffering. Animal rights is not just a philosophy — it is a social movement that challenges society’s traditional view that all nonhuman animals exist solely for human use. As PETA founder Ingrid Newkirk has said, “When it comes to pain, love, joy, loneliness, and fear, a rat is a pig is a dog is a boy. Each one values his or her life and fights the knife.”

Only prejudice allows us to deny others the rights that we expect to have for ourselves. Whether it’s based on race, gender, sexual orientation, or species, prejudice is morally unacceptable. If you wouldn’t eat a dog, why eat a pig? Dogs and pigs have the same capacity to feel pain, but it is prejudice based on species that allows us to think of one animal as a companion and the other as dinner.


Cruelty to animals refers to treatment or standards of care that cause unwarranted or unnecessary suffering or harm to animals. There are many different reasons why individuals abuse animals. Animal cruelty covers a wide range of actions (or lack of action), so one blanket answer simply isn’t possible. Each type of abuse has displayed certain patterns of behaviour that we can use to help understand more about why people commit the crimes we encounter today. Animal cruelty is often broken down into two main categories: active and passive, also referred to as commission and omission, respectively. Passive cruelty is typified by cases of neglect, where the crime is a lack of action rather than the action itself. Examples of neglect are starvation, dehydration, parasite infestations, allowing a collar to grow into an animal’s skin, inadequate shelter in extreme weather conditions, and failure to seek veterinary care when an animal needs medical attention.

Active cruelty implies malicious intent, where a person has deliberately and intentionally caused harm to an animal, and is sometimes referred to as NAI (Non-Accidental Injury). Acts of intentional cruelty are often some of the most disturbing and should be considered signs of serious psychological problems. This type of behaviour is often associated with sociopathic behaviour and should be taken very seriously.


1. How do you understand Peter Singer’s statement: “The basic principle of equality does not require equal or identical treatment; it requires equal consideration” (see the text “Why Animal Rights?”). Do you agree with it?

2. Do you believe that lack of care towards animals can be regarded as animal abuse?

3. Do you think that individuals who are cruel to animals are socially dangerous?

4. Which of the following human activities can be classified as animal abuse:

· using animals in experimentation (in medicine, pharmacology, testing cosmetics, etc.);

· vivisection;

· using animals for entertainment (circuses, film making);

· using animals for food;

· killing animals for their skins, fur, etc.;

· using animals in sports (horse racing, corrida, etc.);

· hunting, whaling;

· pets’ sterilization;

· keeping wild animals in captivity (zoos);

· killing pests (sewer rats, house mice, garden slugs, etc.)

5. Why should people be concerned about animal rights and neglect the rights of other living beings, such as plants, fungi, etc.?
