Tranio:   Mi perdonate, gentle mine.

I am all affected as yourself,

To suck the sweets of sweet philosophy.

Only, good master, while we do admire 

This virtue and this moral discipline,

Lets be no stoics nor no stocks, I pray, 

Or so devote to Aristotle's checks

As Ovid be an outcast quite abjured.

Balk logic with acquaintance that you have,

And practice rhetoric in your common talk . 

Music and poesy use to quicken you;

The mathematic and metaphysics,

Fall to them as you find your stomach serves you.

No profit grows where is no pleasure ta'en.

In brief sir, study what you most affect. 

William Shakespeare

The Taming of the Shrew, Act I, Scene I
