Natural Law


Est. 2018

In dulcedine societatis quaerere veritatem (Latin: Seeking the truth in pleasant company)

This is a series of meetings addressed to academics, doctoral and undergraduate law students and legal practitioners, as well as to non-lawyers – to anyone interested in what law really is. Our goal is to go beyond the reductionist understanding of law as merely the provisions of positive law.
The meetings consist of a lecture by an invited guest, followed by a question and answer session.
Our speakers are Polish and foreign professors.

Past foreign speakers include prof. Rafael Domingo from Emory University in Atlanta (Georgia, USA), prof. Angel Rodríguez Luño from the Pontifical University of the Holy Cross in Rome, prof. Mark Regnerus from University of Texas in Austin, prof. Judith A. Reisman from Liberty University in Lynchburg (Virginia, USA), dr Pablo Requena from Pontifical University of the Holy Cross in Rome, prof. Ferenc Hörcher from University of Public Service (Budapest), prof. Helen M. Alvaré from Antonin Scalia Law School, George Mason University (Virginia, USA), prof. J. Budziszewski from University of Texas at Austin (Texas, USA) and prof. Pavlos Papadopoulos from Wyoming Catholic College (Wyoming, USA).

With deep regret we inform you that on April 9, 2021 has died prof. Judith Reisman, who was our Guest as part of the Natural Law Series. Please pray for the peace of Her soul.


In the upcoming academic year we are planning both online meetings and we will return to meetings in Solek Academic Center.

Wyoming Catholic College is a small college in the northwest of the United States, established in a small town Lander, cultivating the traditions of classical teaching and learning. Our guest told us about the key principles of this educational system. It shapes the whole human person, not only the intellect, but also the body (hence the frequent trips to the mountains and horseback riding lessons) and the will. It is about growth in both intellectual and moral virtues. Students generally do not use smartphones, but instead read so-called Great Books to participate in the great conversation that has been going on since the beginning of Western civilization. Education understood in this way, aided by growth in the theological virtues (faith, hope, and love), truly liberates a person. Its goal is human happiness on earth and in eternity.

May 27, 2021 (online meeting) – prof. Helen M. Alvaré Professor of Law at Antonin Scalia Law School, George Mason University. Prof. Alvaré teaches Family Law, Law and Religion and Property Law. Prior to joining Scalia Law School she taught at the Columbus School of Law and was an attorney at Stradley, Ronon, Stevens & Young in Philadelphia. She graduated in law from Cornell University School of Law and received her MA in Systematic Theology from the Catholic University of America. More: Topic of the meeting: „Parents’ right to raise their children as they wish”.

According to prof. Alvaré, the social situation in the USA has changed significantly in recent years. There is a real obsession with sexuality and the LGBTQ+ movement. Over the past 10 years, American teens have seen a 500% increase in approval for the movement’s demands. Many indoctrinated Americans view the family and the Catholic Church as enemies of freedom. Parents may not send their children to the so-called school sex education, extremely vulgar, but unfortunately most parents are passive and do not oppose it. It is true that over 40 states do not allow the so-called sex change in adolescents, but 89 American universities already offer students this type of treatment (surgery and hormone therapies), which happens without the consent or even knowledge of parents. In October, John leaves home to study, and in November, Kathy is coming to visit his parents. On the other hand, in terms of adoption, sometimes discrimination is made against adoption agencies that are opposed to entrusting children to persons suffering from sexual identity disorders. If the Equality Act enters into force, there will be no normal conditions for the functioning of Catholic institutions, and there are quite a few of them in the US (600 hospitals, 220 universities and 200,000 schools). However, home schooling is developing well. It has more and more opportunities for development due to the growing ideological indoctrination in schools (vulgar sex education, cancel culture, critical race theory, etc.). Migration of people to the so-called conservative states (eg Mississippi, Tennessee, Louisiana, Wyoming, Texas, South Dakota, North Dakota) which – according to prof. Frank H. Buckley, law professor at George Mason University, author of a book „American Secession: The Looming Threat of a National Breakup” – may even result in their secession. It is extremely important to work out and publicly articulate a common, unified position in the above scope in order to stop and then withdraw the destructive effects of a moral revolution.

May 6, 2021 (online meeting) – Marcin Beściak, MA, b. 1990, graduate of the MISH department of the Jagiellonian University and the Institute of Classical Philology at the University of Warsaw, currently a PhD student (he is preparing a dissertation on the Renaissance exegesis of the Old Testament). Professionally translator from Latin, German, French and Italian. He deals in particular with translations of the works of St. Thomas Aquinas. Currently involved in the edition of the Opera Omnia of St. Thomas in Polish – a project implemented by the Thomistic Institute and the Dominican School of Theology Foundation.
Topic of the meeting: The Treatise on Natural Law by Luigi Tapparelli d’Azeglio, SJ – selected issues. The „Theoretical Essay on Natural Law” is a treatise on moral philosophy, focused especially on the theory of society, state and law in the Catholic approach. The pioneering nature of this study lies in the fact that, although it was written in the first half of the nineteenth century, the author uses the classical thomistic method, which at that time (especially in the field of philosophy or moral theology) was not at all obvious or common. The basic text is a theoretical exposition of individual issues from the most basic (what is action, what is the purpose of action, what is a good, etc.) to more complex problems of the epoch (e.g. is the international community a natural society, the limits of the rights of civil authorities, on the form of governance, criticism of democracy as a utopian system, etc.). The attractiveness of this work for today’s reader may lie, for example, in the fact that the author rejects the idea of ​​a social contract as the source of law and state, while demonstrating that civil authority is, in a way, an extension of the father’s power over his own family, so the state and law are part of the (objective) order of nature intended by the Creator, and not a product of the subjective will of the citizens themselves. On the other hand, Taparelli, as a precursor of the social doctrine of the Church and the creator of the concept of social justice, can be a valuable source of arguments for a Catholic in discussions with both liberals and social darwinists, as well as socialists. The lasting value of the „Essay on Natural Law” is best evidenced by the fact that it was inspired by both Leo XIII in the encyclical „Rerum Novarum” and John XXIII in „Pacem in terris”.

The meeting was held in Polish.

February 11, 2021 (online meeting) – dr Pablo Requena – priest of the Prelature of the Holy Cross and Opus Dei. He graduated in medicine and obtained a PhD in moral theology. He lectures on bioethics at the Department of Moral Theology at the Theological Faculty of the Pontifical University of the Holy Cross in Rome. Member of the Pontifical Academy Pro Vita, delegate of the Holy See to the World Medical Association – the largest medical organization in the world, associating national medical organizations from over 100 countries of the world. Topic of the meeting: „Physician in the face of demanding eugenic abortion”. The meeting was translated from Spanish into Polish.

Today, the problem of abortion is primarily a problem of contemporary culture. She argues that abortion is the solution to the problem. Meanwhile, since the Hippocratic oath, already in 450 BC, it stated that I would not give a lethal poison to anyone, even on demand, nor would I advise anyone about it, nor would I ever give a woman a remedy for miscarriage. In many countries, doctors often immediately suggest an abortion as soon as a small problem arises in the course of the pregnancy. Today in the US 30% of women over 45 have had an abortion, sometimes several. You can vote something in parliament, but if the dominant culture is not conducive to the protection of life, sooner or later this protection will be limited. Therefore, the role of culture is irreplaceable.

In the discussion about abortion, extreme, exceptional situations are emphasized above all, constituting 1% of all cases. Thus, 99% of abortions, performed – in many countries – most often on request, are beyond our interest.

In order to improve the level of protection of unborn children and to change the vector of the dominant culture by showing that abortion is not a good solution, it is worth getting involved at various levels, including in a private setting, talking to your relatives and friends, and offering help in difficult situations.

The speaker also drew attention to point 99 of John Paul II’s encyclical „Evangelium vitae”, in which the Holy Father addresses women who have had an abortion.

In the context of the protection of life, the problem of euthanasia was also raised. It is accepted less frequently in parliaments than abortion. When a society introduces euthanasia into the legal system, it shows that it has little solidarity with sick people, because it puts them – and in a difficult life situation, in illness and sometimes loneliness – in the face of the necessity to choose life or death. In this way, many people choose to euthanize which they would not have chosen if it were not possible.

Even Herbert Hendin, a professor of psychiatry at the New York Medical College, an agnostic advocating some euthanasia cases, believes that more involuntary euthanasia is taking place in the Netherlands today than voluntary. His article „The Dutch Experience” is well-known, where he shows that in certain diseases, euthanasia, from something initially unique, has become rather a „norm”, a common way to end the lives of patients. Currently in the Netherlands it accounts for 5% of the causes of death (7,000 annually).

January 18, 2021 (online meeting) – prof. Judith A. Reisman from Liberty University (Virginia, USA). Prof. Reisman has focused most of her work on fighting pornography as a pandemic and exposing abuse in Alfred C. Kinsey’s research. Her book „Kinsey: Crimes and Consequences” was recently translated into Chinese. She is the founder and director of the Reisman Institute, which aims to inform the public about the difficulties faced by children as a result of aggression of overt sexuality. Subject of the meeting: „The history of the sexual revolution in the USA in 1945-2020”.

Prof. Reisman drew attention to Alfred Kinsey’s use of innocent children for his experiments. She pointed to the abuses committed by him. She called him the father of the sexual revolution in the United States. Using examples of newspapers and publishing houses, she presented the change that had taken place in America in the last few decades, especially since the 1970s. The main goal was to sexualize young children. According to the leaders of the sexual revolution, a 7-year-old child can and should engage in sexual activity. Over time, what used to be punished is now taught in schools (e.g. abortion or homosexuality). There has been an extraordinary invasion of pornography. In order to make a positive breakthrough, it is necessary to objectively and comprehensively inform the society about the dire consequences of the sexual revolution both for the general public (breakdown of bonds and destruction of the family) and for the individual (mental disorders and decreased creative potential), striving to engage in a debate that apparently does not want its spokesmen for fear of showing its real consequences.

December 7, 2020 (online meeting) – prof. Mark Regnerus, professor of sociology at the University of Texas at Austin (Texas, USA). He recently published two books in Oxford University Press: The Future of Christian Marriage (2020) and Cheap Sex and Human Transformation, Marriage and Monogamy (2017). He collaborates with First Things, National Review and Public Discourse. The subject of the meeting: „Does it make sense? Same-sex relationships through the eyes of an American sociologist.” The meeting was held in English without translation.

Prof. Regnerus raised several important points. There is a change of language, a change in the meaning of words (e.g. marriage, freedom, equality), which always precedes legal changes. Legal changes last many years and are often the result of litigation conducted by activists. The abbreviation LGBT used contains conflicting tendencies, as the letters LGB denote tendencies that do not question the existence of sex, while in the case of the letter T it is different. Regarding the letter T, the speaker pointed out that this tendency does not appear from early childhood, during which someone accepts his sex, but only in the teenage years, when a young person encounters this type of possibility in the media space. Same-sex partnerships are an attempt to copy marriage, but due to the biological inability to have children and the lack of male-female complementarity, they are unnatural and, to the limit, forced by constant media, political and legal pressure. If this pressure were to cease, the problem would largely disappear by itself, because such relationships – unlike marriage – are not public but purely private, social. The state as such has no interest in institutionalizing them and giving them privileges similar to those enjoyed by marriage, since these unions do not give rise to children who are social capital for the future. In this type of relationship there is no total commitment like in marriage, it is very common to change partners and there is no expectation of children. The rule is that after the death of the partner, the family of the deceased does not maintain any contact with the living partner of their relative. It is quite different in families, where relatives of the deceased spouse often help a surviving widow or widower and still consider him a member of the family.

October 29, 2020 (online meeting) – dr hab. Cezary Kościelniak from the Department of Economic Ethics at the Faculty of Anthropology and Cultural Studies at the Adam Mickiewicz University in Poznan (Poland). Theme: „University and its influence on culture”. In his last book, „Changes in the idea of ​​the university” (PWN 2020), our guest asks questions about the mission and program of the university and the way of education. Elites are essential for proper social development. However, they should serve society for the common good, for the good of every human being. We miss university life in the form of spending more time with professors and students, being together, talking and eating together. In this way a real academic community is created. Small, elite universities can be a good idea. However, they must have a solid economic basis. The meeting was held in Polish.

September 15, 2020prof. dr hab. Mateusz Stróżyński from the Institute of Classical Philology of the Adam Mickiewicz University in Poznan (Poland). Topic of the meeting: „The evolution of the concept of nature in antiquity, the Middle Ages and modern times”. Extremely interesting and accessible, our guest talked about the normative approach to nature as the essence of man and at the same time the obligation and ideal to be implemented, and about departing from it in modern times. He drew attention to the necessity of internal struggle in order to realize his nature. The fact that there are – even numerous – people who behave badly does not mean that bad conduct is human nature. Today, the phrase „be natural” is most often understood as „be spontaneous”, „do what you want”. This is because today nature is often identified with emotionality, feelings, but not with reason and seeking goodness. In order to be truly happy, every person should act in accordance with his nature, understood not only as feelings, which are very changeable, but also have to reflect, reflect on where the real good is and thus realize his nature. In this way, each of us opens up a passionate panorama of working on ourselves, our daily struggle to be truly ourselves by fighting our weaknesses, organizing and properly directing our feelings in order to realize who we really are. The meeting was held in Polish.

June 23, 2020 (online meeting) – dr. hab. Paweł Skibiński, assistant professor at the Department of History of the 20th century at the Institute of History, University of Warsaw (Poland).
