During the Eighteenth century, were art, music, and literature

Question

Suppose to affect audiences mainly in the heart or head?

Answer 1

Both! An example would be Robert Burnsm who wrote in the Scottish dialect.

O, my luve's like a red, red rose,

That's newly sprung in June.

O, my luve's like the melodie,

That's sweetly play'd in tune.

As fair art thou, my bonie lass,

So deep in luve am I,

And I will luve thee still, my Dear,

Till a' the seas gang dry.

Till a' the seas gang dry, my Dear,

And the rocks melt wi' the sun!

O I will luve thee still, my Dear,

While the sands o' life shall run.

And fare thee weel, my only Luve,

And fare thee weel a while!

And I will come again, my Luve,

Tho' it were ten thousand mile!

But I think it's fair to say that a lot of 18th C. poetry was largely intellectual (I think of Alexander Pope). The Romantic movement of the early 19th century (like John Keats) brought personal perspectives and emotion to the forefront.
