1. Introduction

Inequalities may be regarded as differences that are deemed unfair^[1]. Inequalities are multidimensional, not limiting to neither just one sector of society, nor a single resource, nor a single variable. Inequalities have a systemic and relational nature when addressing the causes and their effects^[1]. The multidimensional component of inequalities values vital inequalities, i.e., inequalities in terms of life, death and health; existential inequalities, i.e., unequal recognition of human individuals as persons; resource inequalities, i.e., unequal distribution of resources. Inequalities in terms of resources include dimensions such as inequalities in income and wealth, education and professional qualification, cognitive and cultural skills, hierarchical position in organisations and access to social networks^[2][3][1].

Inequalities in contemporary societies are global inequalities. They are characterised by the growing presence, in the multiple inequalities observable in local contexts and national societies, and shaped by global asymmetric social relationships; inequalities between countries, as they establish and evolve in the contemporary world in profound globalisation; social inequalities on a planetary scale, encompassing or traversing human society as a whole, in a context of globalised social interdependencies^[2].

Currently, and with a growing presence in the future, the digital permeates the lives of practically all of us, and Society 5.0 is an example of a possible materialisation^[4]. Society 5.0 is a recent concept, built on the notion of the functioning of a smart society based on the mobilisation of digital technology and artificial intelligence, adding to the social development and the consequent improvement in individuals’ quality of life, as well as to sustainability ^[5][6][7].

This progressive prominence of the digital necessarily entails a transformation of societal life at the micro (individual), meso (group/organisational) and macro (global) social levels^[4], with a profound influence on social interactions and structures.

This change has positive and/or negative consequences that can themselves shape new and profound social inequalities in a type of society that is sometimes presented as increasingly inclusive^[7]. In this regard, Nadolu and Nadolu (2020)^[8] maintain that

The digitalization of everyday life has become a common place reality for more than half of the global population. Being connected 24/7 on several devices, being only one click/touch away from a huge amount of digital content, being available for interactions with almost any users from around the globe have become routine. In this paper, we identify the main sociological dimensions of the so-called Homo interneticus — a new manifestation of the human condition — on the basis of new communication technologies (p. 1).

However, the digital is not impartial or neutral, either in access or in the use of the digital. Digital literacy or competence to handle it as a consumer, but also as a creator, consciously and intentionally, with digital technology in professional and non-professional daily life, is not guaranteed^[9][10][11]. The promotion of abilities and competences in the digital world is not ensured even in new generations^[9][12]. The disparities in the access to digital technology persist, and this gap calls into question the participation of citizens in decision-making processes.

The induced digital gap defines the degree of digital citizenship for which, unified policies have yet to be drawn at various educational levels to reduce that gap. The quest for a broad participation to develop digital citizenship competencies needs further investigations into innovative educational approaches, pedagogical methods, and routine practices that foster digital literacy, and narrows the digital divide^[13].

Sociology may offer an important contribution by promoting theoretical and methodologically oriented empirical research on the dynamics of Society 5.0 and, potentially, develop relevant strategies and instruments in shaping political decisions in the process of fighting inequalities in the digital society. Ferreira and Serpa (2017)^[14] put forward four of the main structuring principles of Sociology as scientific knowledge, depicted in Table 1.

Sociology, as a form of scientific knowledge, can be defined as “a scientific discipline that perceives in its specific way the social reality, producing plural theoretical topics, formulating research problems within the context of these topics, and developing methodical strategies that guide empirical research”^[14]. The critical basis of this definition, as already put forth by Durkheim, is to explain the social through the social (Figure 1).

Thus, Sociology, together with other social sciences, due to the above-mentioned features, can provide relevant contributions to the promotion of smaller inequalities in increasingly digital societies, by fostering greater awareness of these inequalities and by promoting digital literacy competences. Digital literacy is regarded as

[…] the awareness, attitude and ability of individuals to appropriately use digital tools and facilities to identify, access, manage, integrate, evaluate, analyse and synthesize digital resources, construct new knowledge, create media expressions, and communicate with others, in the context of specific life situations, in order to enable constructive social action; and to reflect upon this process^[15].

Sociology may have heuristic potential in the development of a more balanced society, adding to a development that materialises the potential of this digital society, which is increasingly important in defining the individual’s social positioning, in a sociologically informed society.
