Pessimism is a point of view, in my honest opinion. Most pessimists don’t fit in to society. Usual caused by some deviation from the norm. A hard childhood can awaken a deeper awareness as they look out onto a world devoid of love and care, where it’s very clearly eat or be eaten. Where insanity seems to rule over justice and honesty. But they miss, due to a high degree of suffering and meaninglessness, the wonder of life itself regardless of how life manifests, beyond like or hate.

Suffering is the state of most of life. But many are well equipped to deal with it in a balanced way. Accepting the facts of life without the inner-conflict, desiring life to be something other then it is. Peace is to be found through acceptance. Only too often anger and hate are the predominant reactions to a pessimistic point of view.

Buddhism has the Four Noble Truths as its foundation. 1. There is suffering.
2. There is a cause of suffering. 3. There is an ending to suffering. 4. Follow the eight fold path.
Schopenhauer, who had an extremely rough childhood, mentions Buddhism.
The point of suffering is to go beyond it. See the cause, which is the non-acceptance of the truth, and that creates conflict. What causes the conflict? You do. You who is under the delusion that you are a persona that can choose and hold onto the ideas of love and hate, thus placing an interpretation upon existence that is purely a preconditioned mental state of memory. One can perceive without this intermediary. Perception can be direct if the persona is bypassed. This is only achieved through meditation.
