If the being whose meaning Heidegger seeks seems so elusive, almost like no-thing, it is because it is not an entity. “Being is essentially different from a being, from beings.” The “ontological difference,” the distinction between being (das Sein) and beings (das Seiende), is fundamental for Heidegger.

The philosophical science of ontology, however, considers only those kinds of being which are present in all the special sciences together and is considered as being in general or being as such. From the viewpoint of ontology, then, being can be classified as real being, ideal being, and logical being.

Ancient humans: What we know and still don’t know about them

• Homo habilis (“handy” man)
• Homo erectus (“upright man”)
• Homo neanderthalensis (the Neanderthal)
• The Denisovans.
• Homo floresiensis (the “hobbit”)
• Homo naledi (“star man”)
• Homo sapiens (“wise man”, or “modern humans”)

In philosophy, being means the material or immaterial existence of a thing. Anything that exists is being. Ontology is the branch of philosophy that studies being. Being is a concept encompassing objective and subjective features of reality and existence.

Nothing doesn’t look like anything, not even a void. This is because, if you were to truly experience nothingness, you would have no sight to see anything. You wouldn’t even experience consciousness because that’s a thing. It would be a complete and utter non-experience.
