On our contemporary Odyssey to “Who are you” we arrived for our fourth stage “facts and logic” in Florence.
Why do we start our stage “facts and logic” in Florence?
The emergence of the first facts and logic in people is shrouded in mystery . How did mankind for the first time become consciously aware of a fact? When using a stone as a melee weapon or during love feelings for descendants? How did mankind for the first time consciously notice a logical link? When consciously eating plants with specific properties or on foreseeing pregnancy after sexual intercourse? We do not know.
At this fourth stage, we wish to avoid the world of religion  – or where people fall back upon when interpretation should be given to the unknown, because at other stages during our quest we will address religion adequately.
Due to time constraints, we also ignore the genesis and further development of philosophy in ancient times .
Our fourth stage “facts and logic” starts at the transition from the medieval Scholasticism  to the Renaissance. Both philosophies have attempted to consider the world as deterministic, that is: when the principles and the internal rules are known, then the past, the present and the future are determined. Both philosophical currents had made every effort to determine the order and the internal rules to get grip and insight into our world centred around God  within the Scholasticism, or around mankind and human reason within the ruling elite in the Renaissance .
From the beginning, Christianity has never stopped to debate the relationship between truth revealed from God in the Holy Scriptures and the continuous discovery of truth and facts by human reason – also seen as a gift of God within the Christian faith ; these debates reached their peak in expansion and complexity during the heyday of Scholasticism.
At the beginning of the Renaissance in and around Florence the origin for the discovery of the actual reality permanently shifted from the revelations by God in the Holy Scriptures to human reason centred around mankind. According to the Old Testament the earth – founded by God – will never move , but around 1600 AD Copernicus  and Kepler had conclusively shown that the earth revolved around the Sun. Galileo Galilei had defended this factual discovery in 1632 AD in his writing Dialogo sopra i due Massimi Sistemi di Galileo Galilei del Mondo Tolemaico e Copernicano (Dialogue from Galileo Galilei over the two main world systems, the Ptolemaic and Copernican) in front of the Church Inquisition. The Christian Church had sentenced him in 1633 AD to house arrest and permanently banned the Dialogo. Over 100 years later – in 1737 AD – Galilei was reburied from a humble graveyard to a tomb in the Basilica di Santa Croce in Florence. In October 1992 AD the name of Galilei was finally purified by the Catholic Church by Pope John Paul II .
The continuum of the transition of Scholasticism into the Renaissance is perceived at our visit to the Santa Maria del Carmine  and in it the Cappella Brancacci located in Piazza del Carmine  in Florence.
The following post will include the report of this visit.
