One of the thorniest problems in contemporary philosophy relates to the very nature of consciousness. Most people _________________________________________________.

To know what pain is, for example, it seems plausible that you need to have experienced

pain yourself. You will then know what it is like to feel to pain since this involves knowledge of

b. first learn about by observing others' sufferings

c. consider consciousness an entirely private phenomenon

d. are heavily influenced by their memory of painful experiences
