Beauty (Noun) is (Verb) easy (Adjective) to appreciate (Infinitive) but (Conjunction) difficult (Adjective) to define (Infinitive).

As (Conjunction) we (Pronoun) look (Verb) around (Adverb), we (Pronoun) discover (Verb) beauty (Noun) in (Preposition) pleasurable (Adjective) objects (Noun) and (Conjunction) sights (Noun) — in (Preposition) nature (Noun), in (Preposition) the laughter (Noun Phrase) of (Preposition) children (Noun), in (Preposition) the kindness (Noun) of (Preposition) strangers (Noun).

But (Conjunction) asked (Past Participle) to define (Infinitive), we (Pronoun) run (Verb) into (Preposition) difficulties (Noun).

Does (Auxiliary Verb) beauty (Noun) have (Verb) an (Article) independent (Adjective) objective (Adjective) identity (Noun)?

Is (Verb) it (Pronoun) universal (Adjective), or (Conjunction) is (Verb) it (Pronoun) dependent (Adjective) on (Preposition) our (Possessive Adjective) sense (Noun) perceptions (Noun)?

Does (Auxiliary Verb) it (Pronoun) lie (Verb) in (Preposition) the eye (Noun Phrase) of (Preposition) the beholder (Noun Phrase)?

A (Article) further (Adjective) difficulty (Noun) arises (Verb) when (Conjunction) beauty (Noun) manifests (Verb) itself (Reflexive Pronoun) not only (Adverb) by (Preposition) its (Possessive Adjective) presence (Noun), but (Conjunction) by (Preposition) its (Possessive Adjective) absence (Noun) as well (Adverbial Phrase).

But (Conjunction) then (Adverb) ugliness (Noun) has (Verb) as much (Determiner) a place (Noun Phrase) in (Preposition) our (Possessive Adjective) lives (Noun) as (Conjunction) beauty (Noun), or (Conjunction) maybe (Adverb) more (Adverb/Comparison).

Philosophers (Noun) have told (Verb Phrase) us (Pronoun) that (Conjunction) beauty (Noun) is (Verb) an important (Adjective) part (Noun) of (Preposition) life (Noun), but (Conjunction) isn't (Verb - Negative) ugliness (Noun) a (Article) part (Noun) of (Preposition) life (Noun) too (Adverb)?

And (Conjunction) if (Conjunction) art (Noun) has (Verb) beauty (Noun) as (Preposition) an important (Adjective) ingredient (Noun), can (Modal Verb) it (Pronoun) confine (Verb) itself (Reflexive Pronoun) only (Adverb) to (Preposition) a projection (Noun Phrase) of beauty (Noun Phrase)?

Can (Modal Verb) art (Noun) ignore (Verb) what (Relative Pronoun) is (Verb) not (Adverb) beautiful (Adjective)?

Poets (Noun) and (Conjunction) artists (Noun) have provided (Verb Phrase) an answer (Noun Phrase) by incorporating (Gerund/Verb-ing) both (Determiner) into (Preposition) their (Possessive Adjective) work (Noun).

In (Preposition) doing so (Gerund Phrase), they (Pronoun) have often tied (Verb Phrase) beauty (Noun) to (Preposition) truth (Noun) and (Conjunction) justice (Noun).

John Keats (Proper Noun), the romantic poet (Noun Phrase), wrote (Verb) in (Preposition) his (Possessive) celebrated (Adjective) ‘Ode on a Grecian Urn’ (Proper Noun), ‘Beauty (Noun) is (Verb) truth (Noun), truth (Noun) beauty (Noun).’

Similarly (Adverb), what (Relative Pronoun) is (Verb) beautiful (Adjective) forever (Adverb) remains (Verb) true (Adjective/Noun).

Another (Determiner) meaning (Noun), in (Preposition) the context (Noun Phrase) of (Preposition) the Grecian Urn (Proper Noun Phrase) — an art object (Noun Phrase) — is (Verb) that (Conjunction) truth (Noun) is (Verb) a condition (Noun) of (Preposition) art (Noun)
