We’re talking about that every human being is a survival machine of genes, memes and maybe other units. From this perspective, is there a destiny for every person?
Like Shakespear, his genes, memes and the environment he was born into might be the crucial elements to his success. Are there other elements which lead to his achievement? Are all his personal efforts afterwards pre-destined by the gene, meme and the birth environment? The education and impact he received from the world around him can also be important, but are they also pre-destined before his birth?
There might also be some dynamic things going on which can be taken as coincidences. So are people’s lives just combinations of pre-destined elements and conincidences?
