We are in the position
of a little child
entering a huge library
filled with books
in many different languages.
The child knows
someone must have written those books.
It does not know how.
It does not understand the languages
in which they are written.
The child dimly suspects a mysterious order
in the arrangement of the books
but doesn't know what it is.
That, it seems to me,
is the attitude
of even the most intelligent human being
toward G-d.
We see a universe marvelously arranged
and obeying certain laws,
but only dimly understand these laws.
Our limited minds
cannot grasp
the mysterious force
that moves the constellations.
- Albert Einstein
