Gettier attempts to illustrate by means of two counterexamples that there are cases where individuals can have a justified true belief regarding a claim but still fail to know it because the reasons for the belief, while justified, turn out to be false.

"The best option on a busy* road."
Pedestrian hurries across the "busy" R337 Kingston Road, negotiating heavy traffic.

*Note: "Busy" is a term used by Local Authority engineers to describe a road used by a large number of drivers. The fact that the same road is also used by a large number of pedestrians is of little or no interest to the same engineers. Drivers are busy people. Pedestrians are potential inconveniences to be managed for the benefit of drivers.

An excerpt from Pope Leo XIV's encyclical this morning. The full text can be read here: www.vatican.va/content/leo-...
The principle of social justice

77. For the Christian community, social justice is a concrete way of following Jesus and remaining faithful to the Gospel. In the New Testament, Jesus proclaims the “good news to the poor” ( Lk 4:18) and identifies himself with the lowly, the sick, the imprisoned and strangers (cf. Mt 25:31-46). He thus teaches us that justice is born from, and fulfilled in, fraternity, because the way we approach and relate to the least among us becomes, in concrete terms, the measure of our relationship with God and with our brothers and sisters. Justice, however, concerns not only the behavior of individuals, but also the way in which the structures of society are conceived and organized. In this regard, the Second Vatican Council reminds us that every institution is called to serve the human person and his or her dignity. [105] Social justice is, therefore, characterized by the capacity of a social, economic and political order to allow everyone — particularly the weakest — to live a truly dignified life, without leaving anyone behind.

78. The recent Magisterium has insisted that social justice begins with the least among us. Saint John Paul II spoke of a preferential option for the poor [106] that must guide both personal and societal choices, while Pope Francis denounced a “‘throw away’ culture” [107] that generates ever new forms of exclusion. From this perspective, social justice requires us to look at individuals and communities, starting with the most vulnerable: the poor, migrants, refugees, internally displaced persons, victims of violence and people living in urban or existential peripheries.79. The idea of “social justice” helps us recognize that injustices do not arise solely from the wrong choices of individuals, but also from structures, mechanisms and economic and cultural systems that produce inequality almost automatically. Saint John Paul II spoke in this vein of structures of sin [108] that oppose God’s will and require a commitment to personal and social conversion. In this perspective, justice is not merely about the fairer distribution of resources or the correction of current injustices, but also assumes a restorative dimension. It aims to mend broken bonds and reintegrate those who have been excluded, taking into account the wounds caused by injustices, such as wars, colonialism, racial or gender discrimination, violence against entire peoples and exploitation. This may include restoring dignity and a voice to those who have been ignored, fostering processes of healing for collective memory, opposing discriminatory laws and practices, and providing concrete support to those who still bear the consequences of wrongs suffered in the past.

80. In this day and age, social justice must also grapple with the environment shaped by digital technologies. The spread of global networks, platforms and artificial intelligence systems is changing the way we obtain information, communicate and access services. Justice demands that we prevent the emergence of new forms of exclusion and deprivation of freedoms: individuals and peoples hindered or denied access to basic technologies, communities exposed to invasive surveillance and social groups penalized by opaque algorithms that perpetuate prejudice and discrimination.In the digital age, a just social order guarantees everyone equal access to opportunities, protects the youngest and weakest members of society, combats hate and misinformation and subjects the use of data and technology to public oversight, so that the guiding principle is not solely profit but the dignity of every person and the common good of all people.

81. A litmus test for social justice today is the treatment of migrants, refugees and those forced to move due to poverty, violence, climate change and environmental disasters. The way a society treats them reveals whether its sense of justice is driven by fear or by the spirit of fraternity. Pope Francis urged us to see migrants not simply as a problem to be managed, but as a living image of the People of God on the move. [109] They are people with dignity, resources and dreams, who have the right to be treated with respect and to ask to become active members of the societies that welcome them. Social justice in this area entails at least two complementary commitments. On the one hand, this means protecting the rightful hopes of those forced to leave by ensuring safe and legal routes, dignified conditions for receiving them, and genuine pathways to integration. On the other hand, it means promoting the right to remain in one’s homeland in peace and security by addressing the root causes that force people to migrate, including those linked to economic injustices and the climate crisis. When these rights are respected, migration can become an opportunity for encounter and mutual enrichment among peoples.
