The main problem with pragmatism as a life philosophy is that we can never know enough to infallibly predict the outcomes of our “pragmatic” behavior–especially if/when it involves how others react to our “pragmatism.”
The second most difficult problem for pragmatism as a life philosophy is that we (none of us) are as smart as we think we are. No, not one.
If only we were omniscient or something. . . Yeh, that would help.
Proverbs 3:5-6
5 “Trust in the Lord with all thine heart; and lean not unto thine own understanding. 6 In all thy ways acknowledge him, and he shall direct thy paths.”
