according to keats what makes man love life inspite at all its problems and mysteious?

According to Keats, anything that is beautiful makes life worth living. This notion of the poet is portrayed through the first line of the poem "Endymion", "A thing of beauty is joy forever". The poet believed that life in spite of its miseries and sorrows is worth living because of the beautiful things surrounding us. Staying true to the Romantic tradition, "beauty" here implies the beauty and bounty of Nature. Keats strongly believed that Nature alone helped us realize the true meaning of life and thus, it is to Nature we must turn for love and solace.
