All Ideas: All minus descriptions. From 30 Philosophers: “An idea in everyday conversation is a mental construct that describes something. It is a bit nebulous and overarching, so I use it in that manner. In the Idea of Ideas framework:

“An Idea is a mental construct that stems from impressions, describing concrete objects or abstract entities of the material world or beyond.”

Notice ideas stem from impressions, but do not originate from them. They are not direct live impressions; live impressions of the senses do not directly become ideas. Ideas are a result of recalled impressions involving cognitive processes. When a recalled impression manifests as a memory paired with interpretation or labeling, it qualifies as an idea. For instance, merely revisiting the raw sensation of anger is not an idea. But when you feel that anger and label it as bad, it evolves into an idea. When you are startled, that’s not an idea. The urge to run because you are startled, that’s an idea.”

  • Empirical Ideas: Direct observations of the universe.
  • Rational: Indirect ideas about empirical ideas.
  • Irrational: New ideas, speculation, and the disproven.
  • Rediscoveries: Forgotten, then returned to our “current” Grand Rational Framework of common knowledge.

Heidegger’s Existentialism
Heidegger’s Existentialism
Heidegger's existentialism centers on the concept of "being-there" (Dasein), which refers to the unique way humans exist and relate to the world. Heidegger explores the nature of being and emphasizes the importance of understanding one's own existence within the context of time and space. His philosophy delves into the idea of being authentic by confronting the inherent uncertainties and anxieties of life, and seeking a deeper understanding of one's place in the world through introspection and connection to nature.

Sartre’s Existentialism
Sartre's existentialism emphasizes individual freedom, choice, and responsibility. It posits that existence precedes essence, meaning that individuals are not defined by any preexisting essence but instead create their own essence through actions and decisions. Sartre's philosophy focuses on the concept of "bad faith," where people deny their freedom by conforming to societal expectations, and encourages living authentically by embracing one's freedom and making deliberate, conscious choices.
Existence precedes essence.
