Taste

Taste is one of the most common and fundamental of the senses in life on
Earth. It is the direct detection of chemical composition, usually through
contact with chemoreceptor cells. Taste is very similar to olfaction (the
sense of smell), in which the chemical composition of an organism's ambient
medium is detected by chemoreceptors. In a liquid medium, taste is often
used to describe this act as well.

In humans, the sense of taste is conveyed via three of the twelve cranial
nerves. The facial nerve (VII) carries taste sensations from the anterior
two thirds of the tongue, the glossopharyngeal nerve (IX) carries taste
sensations from the posterior one third of the tongue while a branch of the
vagus nerve (X) carries some taste sensations from the back of the oral cavity.

Taste in aesthetics

Taste can also refer to one's appreciation for aesthetic quality. Paul
Graham notes, "I think it's easier to see ugliness than to imagine beauty.
The recipe for great work is: very exacting taste."
