Evangelii Gaudium §232

232. Ideas – conceptual elaborations – are at the service of communication, understanding, and praxis. Ideas disconnected from realities give rise to ineffectual forms of idealism and nominalism, capable at most of classifying and defining, but certainly not calling to action. What calls us to action are realities illuminated by reason. Formal nominalism has to give way to harmonious objectivity. Otherwise, the truth is manipulated, cosmetics take the place of real care for our bodies.[185] We have politicians – and even religious leaders – who wonder why people do not understand and follow them, since their proposals are so clear and logical. Perhaps it is because they are stuck in the realm of pure ideas and end up reducing politics or faith to rhetoric. Others have left simplicity behind and have imported a rationality foreign to most people.
