Being is, for parmenides, something which does not exist. Light is not the opposite of darkness. In the essence of light, darkness is destroyed and overcome.
Being is, along with non-being, a mere abstraction of thought which arises when becoming is analyzed. There is ultimately becoming.
Being and Time can be summed up in three linesa ham sandwich is better than nothing; nothing is better than God; therefore, a ham sandwich is better than God
Being is a wrongheaded notion based on the idea that there are subjects standing opposed to some substance. If we get rid of the presumption of the 'subject' then we also rid ourselves of the precondition for substance. We thus acquire 'degrees of being' in place of the confused idea of things which have being.

Being is a sphere entirely opposite from knowing, insofar as it is absolutely impossible for a subject to see or have insight into something while leaving itself out of the picture.
Being is, along with truth, a thing without a fixed nature readily accessible to us. We give different accounts of both at different times, and what they are at any given time depends in part on our questions and answers about them.
Being is absolutely immanent. Redemption is not any 'outside' but an always determinate 'inside.
