(no subject)

As for the terms 
                 good 
                       and bad, 
they indicate 
             no positive quality 
in things 
           regarded in themselves, but

are merely modes 
                     of thinking, 
or notions 
           which we form 
                         from the comparison 
of things 
             one with another. 

Thus 
      one and the same 
                         thing 
can be 
        at the same time 
            
good, 
bad, 
and 
indifferent. 

For instance, music 
                  is good for him 
                              that is melancholy, 
bad for him 
            that mourns; 
for him 
          that is deaf, it is 

neither 
good
nor 
bad.
