Rationaalisessa

Rationaalisessa is the inessive singular form of the Finnish adjective rationaalinen, meaning rational or based on reason. It is used to describe something located within or defined by rationality, or to indicate a context characterized by rational principles. As an inflected form, rationaalisessa typically appears in phrases that denote “in the rational sense” or “in a rational framework.”

In practice, rationaalisessa appears in philosophical, scientific, or academic prose, as well as in more general discourse when emphasizing a rational approach. Common contexts include expressions such as rationaalisessa ajattelussa (in rational thinking), rationaalisessa mielessä (in the rational sense), and rationaalisessa maailmankuvassa (in a rational worldview). The word is often paired with other terms to specify the scope of rationality, for example during discussions of method, argumentation, or decision making.

Relation to other forms: the adverbial equivalent is rationaalisesti (rationally). The phrase rationaalisessa is one of several inflected forms used to express location or state within rationality, and it is typically contrasted with more intuitive, emotional, or irrational contexts.

Usage note: rationaalisessa does not denote a separate philosophical doctrine. Rather, it functions as a grammatical form that enables precise description of perspectives, arguments, or settings that are framed as rational. Its meaning is thus closely tied to the broader concept of rationality in Finnish language and discourse.
