Answer:The 1987 Philippine Constitution shows influences from three major thinkers: - Hobbes: The strong presidency reflects Hobbes' belief in a powerful leader to maintain order. The emphasis on law and order also aligns with his ideas. - Locke: The Bill of Rights (protecting rights like life and liberty) and the system of checks and balances show Locke's ideas of natural rights and limited government. The idea that power comes from the people (popular sovereignty) is also Lockean. - Rousseau: The concept that the government's power comes from the people (social contract) and the emphasis on citizen participation in government reflect Rousseau's ideas.
