Giovanni Botero (c. 1544 – 1617) was an Italian thinker, priest, poet, and diplomat, best known for his work Della ragion di Stato (The Reason of State). In this work, Botero argued against the amoral political philosophy associated with Niccolò Machiavelli's The Prince, not only because it lacked a Christian foundation but also because it simply did not work. Basing his political and economic ideas primarily on the thought of Thomas Aquinas, Botero argued for a more sophisticated relationship between princes and their subjects, one that would give the people more power in the political and economic matters of the state. In this way, Botero foreshadowed the thought of later liberal thinkers, such as John Locke and Adam Smith.
Born around 1544 in Bene Vagienna, in the northern Italian principality of Piedmont, Botero was sent to the Jesuit college in Palermo at the age of 15. A year later, he moved to the Roman College, he was introduced to the teaching of some of the most influential Catholic thinkers of the sixteenth century, including Juan Mariana, who, in his On the King and the Education of the King, would argue for the popular overthrow of tyrannical rulers.
In 1565, Botero was sent to teach philosophy and rhetoric at the Jesuit colleges in France, first in Billom, and then in Paris. The second half of the sixteenth century saw the kingdom dramatically, and often violently divided by the French Wars of Religion. Paris especially was heating up during Botero's stay there from 1567-1569, and he was recalled to Italy after getting too caught up in the excitement, apparently for his involvement in an anti-Spanish protest.
