This distinction rests on their verificationist theory of meaning, according to which the meaning of a sentence is its verification conditions and understanding a sentence is knowing its verification conditions. For example, knowing the meaning of “This is blue” is being able to pick out the object referred to by “this” and to check that it is blue. While this works only for simple sentences built from terms that directly pick out their referents and predicates with directly verifiable content, it can be extended to other sentences. To understand “No emerald is blue” one need only know the verification conditions for “This is an emerald”, “This is blue” and the logical relations of such sentences to “No emerald is blue” (for example, that “no emerald is blue” implies “if this is an emerald, then this is not blue”, and so forth). Simple verification conditions plus some logical knowledge buys a lot. But it does not buy enough. For example, what are the verification conditions expressed by “This is an electron”, where “this” does not pick out an ostendible object and where “is an electron” does not have directly verifiable content?
A research proposal is another kind of a complicated academic writing you may be asked to complete pursuing a degree. It differs greatly from any other dissertation or thesis sample, as it is a practical proposal on some scientific investigation. It may even be of greater importance to your academia than any other paper you have submitted before. The tricky part in writing your research proposal paper is that it has to be 100% unique and original. No one will analyze a partially plagiarized research proposal, as it is supposed to promote a good start to your future career. Thus, you have to make sure you paper is grammatically flawless, well structured, and plagiarism free.
