Can we ever truly know anything? Is there a universal moral truth? What happens after death? Is our perception of reality accurate?

Whether we can know anything for certain, if there are universal moral truths, what happens after death, and if our perception of reality is accurate are fundamental philosophical questions with no universally accepted answers. These are ongoing topics of debate in philosophy and science, with viewpoints ranging from the skeptical to the faithful, and from the scientific to the metaphysical. Different belief systems and philosophical traditions offer varying perspectives on each of these questions. 

Can we ever truly know anything?

• 
  

  Skepticism: Some argue that we are forever confined to our subjective interpretations and cannot know objective truth with certainty. 

  
  

  
  

• 
  

  Certainty: Others argue that while absolute certainty might be elusive for certain matters, we can achieve a high degree of certainty (moral or physical) in most areas through reason and reliable faculties. 

  
  

  
  

Is there a universal moral truth?

• This is a subject of debate with no single answer. 

  
  

  
  

  
  

• Some philosophical and religious traditions posit a universal moral framework or truth, often divinely inspired or based on intrinsic human nature. 

  
  

  
  

  
  

• Others believe that morality is relative, culturally determined, or a social construct, with no objective universal truth. 

  
  

  
  

  
  

What happens after death?

• This question has no definitive, scientifically proven answer. 

  
  

  
  

  
  

• Scientific view: Some scientific perspectives suggest that consciousness ceases to exist upon death, as it is a product of the brain. 

  
  

  
  

  
  

• Religious and spiritual views: Many religions propose some form of afterlife, such as judgment by a divine being, reincarnation, or a spiritual existence. 

  
  

  
  

  
  

• Philosophical views: Some philosophers have argued for the immortality of the soul or mind, though modern philosophy generally links the mind to the physical brain. 

  
  

  
  

  
  

• Faith in life after death is considered a rational and truth-seeking pursuit by some, even without empirical evidence, notes ResearchGate. 

  
  

  
  

  
  

Is our perception of reality accurate?

• Our perception is shaped by our senses, brain, and consciousness, which may filter and interpret reality rather than presenting a direct, objective view. 

  
  

  
  

  
  

• The accuracy of our perception is limited by our biological and cognitive faculties, leading to a subjective experience of reality. 

  
  

  While it's a challenge to know if our perception perfectly aligns with objective reality, we can gain a high degree of certainty through practice and reason, argues
