What virtues facilitate formation of the republic i.e. Republic of the Philippines? The answer to that is shaped by knowledge of what republic means:
Republican government: One in which the powers of sovereignty are vested in the people and are exercised by the people, either directly, or through representatives chosen by the people, to whome those powers are specially delegated.
Democracy. That form of government in which the sovereign power resides in and is exercised by the whole body of free citizens directly or indirectly through a system of representation, as distinguished from a monarchy, aristocracy, or oligarchy.
In a republic the sovereignty is in each individual person.
In a democracy the sovereignty is in the group (the majority).
In a republic, the people enjoy their God-given natural rights (life, liberty, the pursuit of happiness, justice, freedom of speech, religion, press).
In a democracy, the citizens enjoy only government-granted privileges (or, civil rights).
