Algis Valiunas has written one fascinating article on THE theoretical man of the 20th century.
Here’s Einstein on determinism: "Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect as well as for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible player." (Nicely said, you have to admit.)
Here’s Albert on morality: "The most important human endeavor is the striving for morality in all our actions. Our inner balance and even our existence depend on it. Our morality in our actions can give beauty and dignity to life."
Here’s Valinius’ analysis: Einstein "seems finally to live a riven life, one of spiritual incoherence, denying freedom of choice yet preaching an exigent morality."
