This paper aims at pointing out a range of differences between logical form as used in logic and logical form (LF) as used in the minimalist architecture of language. The differences will be shown from different angles based on the ways in which they differ in form and represent some natural language phenomena. The implications as following on from such differences will be then linked to the issue of whether semantic realization in mind/brain is computational. It will be shown that the differences between logical form as used in logic and logical form (LF) as used in the minimalist architecture of language will help us latch on to the realization that there is no determinate way in which semantics can be computational or computationally realized. © 2013 Springer-Verlag.
