Ancient Greeks thought that there exists a consciousness substance and named it Thymos.

"The only incomprehensible thing about the universe
is that it is comprehensible" (Albert Einstein)

"The more the universe seems comprehensible,
the more it seems pointless" (Steven Weinberg)

"The more familiar I get with the universe,
the less familiar I feel with myself" (piero scaruffi).


"O you proud Christians, wretched souls and small,
Who by the dim lights of your twisted minds
Believe you prosper even as you fall,
Can you not see that we are worms, each one
Born to become the angelic butterfly
That flies defenseless to the Judgement Throne?" (Dante, Canto 10, "Purgatorio")


"To do is to be - Descartes
To be is to do - Voltaire
Do be do be do - Frank Sinatra"

"We are born naked, wet and hungry.
Then things get worse."

Last of all, he will be able to see the sun,
and not mere reflections of it in the water,
but he will see it in its own proper place,
and not in another; and it will contemplate it
as it is. (Plato, "Republic")
