Who would be my dream celebrity partner on a deserted desert island?
Instantly I know that I would chose a "celebrity" philosopher and/or religious leader from the past, with whom to while away the time until either rescue or death, discussing life and matters pertaining thereto. My first choice would be the philosopher and saint Thomas Aquinas. I make this choice without regard for the fact that he would likely be very uncomfortable sequestered with and expected to talk to a woman. I chose him enthusiastically because of his writings such as The Existence of God can be proved in five ways which is copied below. Whether in a religious or scientific context or medley of both, this sort of philosophy is what I like to think about. I had his work on my coffee table for all of this year, and I thought it over quite a bit.
(If Plato would discuss his Socratic dialogue, The Republic, 380 BC, concerning justice, etcetera he would be a thrilling second choice. But again, I doubt that he would.)
The Existence of God can be proved in five ways, by St. Thomas Aquinas, born Jan 28, 1225, died Mar 07, 1274 · Fossanova Abbey, Kingdom of Sicily [Italy]
The First Way: Argument from Motion
"Our senses prove that some things are in motion.
Things move when potential motion becomes actual motion.
Only an actual motion can convert a potential motion into an actual motion.
Nothing can be at once in both actuality and potentiality in the same respect (i.e., if both actual and potential, it is actual in one respect and potential in another).
Therefore nothing can move itself.
Therefore each thing in motion is moved by something else.
The sequence of motion cannot extend ad infinitum.
Therefore it is necessary to arrive at a first mover, put in motion by no other; and this everyone understands to be God.
The Second Way: Argument from Efficient Causes
"We perceive a series of efficient causes of things in the world.
Nothing exists prior to itself.
Therefore nothing [in the world of things we perceive] is the efficient cause of itself.
If a previous efficient cause does not exist, neither does the thing that results (the effect).
Therefore if the first thing in a series does not exist, nothing in the series exists.
If the series of efficient causes extends ad infinitum into the past, for then there would be no things existing now.
That is plainly false (i.e., there are things existing now that came about through efficient causes).
Therefore efficient causes do not extend ad infinitum into the past.
Therefore it is necessary to admit a first efficient cause, to which everyone gives the name of God.
The Third Way: Argument from Possibility and Necessity (Reductio argument)
"We find in nature things that are possible to be and not to be, that come into being and go out of being i.e., contingent beings.
Assume that every being is a contingent being.
For each contingent being, there is a time it does not exist.
Therefore it is impossible for these always to exist.
Therefore there could have been a time when no things existed.
Therefore at that time there would have been nothing to bring the currently existing contingent beings into existence.
Therefore, nothing would be in existence now.
We have reached an absurd result from assuming that every being is a contingent being.
Therefore not every being is a contingent being.
Therefore some being exists of its own necessity, and does not receive its existence from another being, but rather causes them. This all men speak of as God.
The Fourth Way: Argument from Gradation of Being
"There is a gradation to be found in things: some are better or worse than others.
Predications of degree require reference to the “uttermost” case (e.g., a thing is said to be hotter according as it more nearly resembles that which is hottest).
The maximum in any genus is the cause of all in that genus.
Therefore there must also be something which is to all beings the cause of their being, goodness, and every other perfection; and this we call God.
The Fifth Way: Argument from Design
"We see that natural bodies work toward some goal, and do not do so by chance.
Most natural things lack knowledge.
But as an arrow reaches its target because it is directed by an archer, what lacks intelligence achieves goals by being directed by something intelligence.
Therefore some intelligent being exists by whom all natural things are directed to their end; and this being we call God."
