Too much of a good thing is a bad thing. Ships founder when overladen with good things, or when a load shifts positions in high seas. Any unforeseen problem can effect the vessel and cause it to list and wain, eventually sinking under its own weight. Poor design can also affect the ships performance.
Horses can founder when they consume too much spring grass containing too much Fructan. Fructan is a sugar stored in grass that is typically saved for future development of the plant and photosynthesis. During early morning and cool overcast conditions grass can contain too much of this sugar the horse cannot process. The Fructan builds up and passes to the large intestine where it creates lactic acid which then delaminates the hoof wall. Sort of a diabetic type process for horses where a sugar overload causes problems and then pH levels become acidotic. Again, what appears to be a normal pasture to most, is highly toxic to reality. 
Religion is constantly switching positions and foundering as well. With too much psychological/chemical/neuro stimulation without reference to reality, feelings are easily manipulated by smooth talk and big promises. Promises that don’t match with reality. Too much bible skews perception and causes its adherents to narrowly assess life through a small prism of archaic contradiction and excuse for changing morals and long explanations of why it was ok. The answer is alway more bible, which entrances the mind, and like any single disciplinary approach, foundering occurs oblivious to the host. The key to understanding the mysteries is unbelief, which is why unbelief is condemned so highly in Abrahamic religion. Monotheism has no room for tolerance, and evidence contrary to faith is easily dismissed without second thought. This is not a virtue, it is an illness. What is thought of as the remedy, is actually the illness. Horses have to change their stance when foundering, which is exactly what we see in religion when things don’t add up. But god never changes? Hmm
Horse changing his stance to relieve the pain in the coffin bone and hoof from laminitis.
