One of the reoccurring questions I receive from Muslims is how to reconcile the finality of Islam, its take on The Truth, and how such a firm stance might be perceived in a society which, at least on the surface level, prides itself on pluralism. In essence, many Muslims have felt pressure to cede ground on the maxim that Islam is the final revelation to mankind. The following is from a conversation I had some years ago, redacted for brevity sake here:
The Truth (incidentally, one of God’s Divine Attributes according to Islam) does not become more or less apparent; it has no variance. It simply is The Truth. What changes is our faculty to comprehend and observe The Truth. This faculty can increase as well as decrease. Likewise, in comparison to mathematical truths, they are equally made no more, or no less, true through our varying efforts to understand them. If one is unable to comprehend a mathematical truth, the problem cannot be assumed to lay in the falsity or improbability of said (mathematical) truth, but rather has an equal probability that it may be our faculty and capacity to comprehend, observe, and articulate said mathematical) truths. In other words, the falsification (i.e., the variance) lies at the feet of the observer and not upon the doorstep of The Truth.
In relation to this, for one who has observed The Truth, it may seldom prove fruitful to convince another about The Truth, for conviction cannot be the stowed from any mortal hand to an equally mortal breast. What is left is only an obligation to inform one’s subject that there is The Truth. From here, one’s obligation shifts from informing the other to placing one’s thoughts and actions in conformity with The Truth.
