A secular age

I am working on a critical reading of this book

Introduction
Taylor mentions three types of secularity


 * 1) Secularity as Public Spaces: This sense of secularity refers to the separation of religion from public institutions and practices, especially the state. In a secular society, political structures are independent of any religious institutions, and religion or its absence is largely a private matter. This perspective also includes the idea that the "public spaces" of society have been emptied of references to God or any ultimate reality. The various spheres of society - economic, political, cultural, educational, professional, recreational - generally operate without reference to God or any religious beliefs.
 * 2) Secularity as Decrease in Religious Belief and Practice: The second sense of secularity refers to a reduction in religious belief and practice, implying that fewer people are believing in God, attending religious services, or practicing religious rituals. This sense is more related to individual and societal religious practices and beliefs, rather than the structure of institutions.
 * 3) Secularity as Condition of Belief: The third sense of secularity focuses on the conditions of belief, meaning the shift from a society where belief in God is unchallenged and unproblematic, to one where it is understood to be one option among others. In a secular society, belief in God is not the default or the norm; it is just one of many belief options available, and often not the easiest one to embrace. This sense of secularity speaks to the diversity and complexity of belief in modern society.
