[
1913 Webster ]
Note : "
This word is employed by English writers in a very loose and improper sense .
It is with them usually convertible into hypothesis ,
and hypothesis is commonly used as another term for conjecture .
The terms theory and theoretical are properly used in opposition to the terms practice and practical .
In this sense ,
they were exclusively employed by the ancients ;
and in this sense ,
they are almost exclusively employed by the Continental philosophers ." --
