After completing his philosophical education at Freiburg, he was made lecturer at Heidelberg in 1905, and he was elected professor there just before the outbreak of World War I.
[2] Lask was an important and original thinker whose rewarding work is little known, due to his early death, but also because of the decline of neo-Kantianism.
His published and some unpublished writings were collected in a three volume edition by his pupil Eugen Herrigel with a notice by Lask's former teacher Rickert in 1923 and 1924.
Lask is of interest to philosophers because of his uncompromising attitude and to historians of philosophy because of his influence on György Lukács and the young Martin Heidegger.
[3] Lask's ideas were also influential in Japan, due to Herrigel, who lived and taught there for several years.
