is no figure in the freedom of conscience domain that
would match the breadth and the scope of Michael Servetus’s
outlook and his importance to the evolution of this outstanding
concept to understand the development of mankind in Western
Europe. Servetus stands out for having left us two outstanding
legacies: the right to free conscience and the freedom
of speech, and the use of radicalism as intellectual method.
Recent historical studies reveal that the ideas of Servetus
on tolerance marked a turning point in the intellectual
discussion which led to the recognition of the freedom
of thought and conscience as an inalienable human right.
His example influenced the works of John Locke and, through
him, the ideas of the statesmen who drafted the Constitution
of the United States of America and its first Amendments.
Servetus was also a radical thinker, devoted to the search
truth above all the established dogmas, and without taking
into account the consequences that this radicalism could
have for his life.
