Yet he never took his own advice. A hypocrite living a lavish life despite saying such a life is meaningless
Schopenhauer actually did not recommend suicide because according to him, it's affirmation of the Will rather than denial of it. Denial of the Will is to be achieved through denying life's pleasures rather than trying to escape suffering, which is actually assertion of the will to live. I suppose that doesn't really matter if suicide ends your existence, but Schopenhauer believed in reincarnation of a sort. The essay "On Suicide" was mostly a defence of Hume's position on suicide and condemnation of how christians at the time punished people who attempted suicide and their families.
You're totally right in calling him a hypocrite though, he didn't exactly practice what he preached in regard to asceticism. Or empathy, since he was a often shithead to the people in his life. That being said, I find "On Suicide" to be very touching and sensitive, it's one of my favourite essays of his.
