| A host of logical papers arise from the discussion of the foundations of semantics, with a number of proposals which generalize or modify Tarski's semantical conception of truth. |
| The meaning of public relations clearly goes beyond these semantical gropings, and it continues to elude even veteran public relations practitioners. |
| As we shall see later on, this semantical blurring is not without importance. |
