The theoretical has value only when it bears upon the practical.<br/><br/>The theoretical has value only in its relevance to the practical.<br/><br/>Hi, <br/><br/>I want to get your expert opinions on whether these two sentences make sense.<br/><br/>Additionally, I want to know if<br/><br/>putting "the" infront of "theoretical" or "practical" to mean "theoretical/practica things in general" is OK. <br/><br/>Thanks
