Courage
Courage is a virtue only when it serves others or a general and magnanimous goal. Courage is not the absence of fear, it is the ability to overcome it with a stronger and altruistic will. It is the will of the spirit, manifested in the face of danger. Courage is not passion, it is a virtue and condition for all virtues.
One need not hope in order to undertake, nor succeed in order to persevere. (William I, Prince of Orange)
Sense
Sense is the stance that enables the right judgement about what is good or bad for someone. Sense is a condition for all other virtues. Sense must direct the three other virtues: moderation, courage and justice. Sense defines what needs to be chosen and what must be avoided.
Sense is love choosing cleverly. (Saint Augustin)
Moderation
Moderation is the instinct for measure, causing us to remain the masters of our desires, instead of being their slaves. It is a pleasure that is free, enjoying even more due to its freedom. Moderation is a virtue for all times, required much more when living conditions are favorable.
The greatest wealth is to live content with little, for there is never want where the mind is satisfied. (Lucretius)
Justice
Justice is the ideal of all virtues and the principle of their co-existence. A perfect virtue. A virtue of unbiased order and fair exchange.
The just are not made by justice, the just ones make justice. (Aristotle)
Perseverance
Perseverance is a virtue that encourages us to overcome the troubles and obstacles and to continue our work and follow our ambitions and goals.
Ambition is the path to success. Persistence is the vehicle you arrive in. (Bill Bradley)
