Answer:
d. To study logic it is important to learn to employ language precisely
Explanation:
Our ability to communicate and be able to express what we have in mind through words is something that has characterized us as living beings.
Being able to schematize our ideas from a linguistic basis is one of the foundations of logic. The language we use carries with it the meaning of our reality, without this part there would be nothing for us.
On the practical level, if a person must speak or think in a language other than the native one, logic and mental flow simply feel natural for that particular language.
Each language has a particular way of categorizing mental concepts. There are data that correlate the learning of multiple languages with the stretching of the plasticity of our brain.
Our conceptual understanding is, at best, tenuous with respect to the logic of language. The circumstantial evidence points to a schematism in human language that is highly restricted, but also very rich and easy.
