It seems so foolish. These are left-wing homosexuals who are demonstrating in support of the Islamification of Europe - when Islam right now in the Middle-East is brutally persecuting homosexuals.
On seeing the picture my first thought was that these people lack prudence. It is another reminder that some people do not have prudence and are therefore not fit for a leadership role in society.
I thought it interesting to look further into the quality of prudence and discovered that it was once considered to be a cardinal virtue. The Wikipedia page on prudence tells us that the word derives from the Latin "providential" meaning "foresight, sagacity" - and this, it seems to me, remains the core meaning of the virtue. It is exactly what the homosexual protesters lack: foresight and wisdom in considering the possible consequences of their demands.
The Wikipedia page also has a section on the "integral parts of prudence". These seem to have been formulated by St Thomas Aquinas, writing in the 1200s. Aquinas adds a great deal to understanding what is required for the virtue of prudence:
The following are the integral parts of prudence:
- Memoria : accurate memory; that is, memory that is true to reality; an ability to learn from experience;
- Docilitas : an open-mindedness that recognizes variety and is able to seek and make use of the experience and authority of others;
- Intelligentia : the understanding of first principles;
- Sollertia : shrewdness or quick-wittedness, i.e. the ability to evaluate a situation quickly;
- Ratio : Discursive reasoning and the ability to research and compare alternatives;
- Providentia : foresight – i.e. the capacity to estimate whether particular actions can realize goals;
- Circumspection : the ability to take all relevant circumstances into account;
- Caution : the ability to mitigate risk.
Given that prudence has so many parts, it shouldn't be a surprise that it does not come equally to people.
There is a very good and more detailed discussion of the virtue of prudence here.
