This could refer to the progress of society, the advancement of understanding, or the enhancement of the human condition. Tolstoy is highlighting the importance of private action and how it can have a positive impact on the world. He is suggesting that although we may not understand it, our private actions become part of a larger, cumulative effort to achieve the universal objectives of humanity.
