Abstract
In The Search after Truths Nicolas Malebranche (1638-1715) claims that the first man, Adam, had the same senses as we do, that he felt the same pleasures and pains as we do, but without being distracted from God. However, after he had sinned, his senses revolted against him and enslaved him, as they do us. In other words, because of the original sin the union that joins our mind to God and which raises us above all material things is weakened by a union with our body, a union that debases us and which is the main cause of all our errors and miseries. This article tries to analyse these errors and miseries in relation to man's search after truth
