&quot;existentialism is concerned with the emptiness, horrors and anxieties of being alive&quot;<p>You&#x27;re mistaken to think so about existantialism.  I suggest you read &quot;Existentialism is a Humanism [1]&quot;, which is a document I&#x27;ve studied very recently and one that I&#x27;ll study again, and one has been influential to me.  Existantialism is an idea based on the hypothesis that man exists without a purpose, without a creator and without predefined values, i.e. he comes to exist before his essence, that which he is responsible of and confined to defining and creating by himself; and that he &quot;in fashioning himself, fashions man&quot;, i.e. with his decisions, he demonstrates what he thinks is apt for all the humanity.  The linked text explains it all better than my humble summary.<p>[1] <a href="https:&#x2F;&#x2F;www.marxists.org&#x2F;reference&#x2F;archive&#x2F;sartre&#x2F;works&#x2F;exist&#x2F;sartre.htm" rel="nofollow">https:&#x2F;&#x2F;www.marxists.org&#x2F;reference&#x2F;archive&#x2F;sartre&#x2F;works&#x2F;exis...</a>
