@sometime sun,
Will is a tricky thing, even to define.
Must one have be cognizant of his/her actions to say that they had a will?
Or must one simply be animate?
If one must simply be animate than all animals have a will and all is not stimulus/response.
I prefer to think of thing this way out of a sense of romance, however, it is a tough call to convince.
Many assume and maybe rightly so that all is simply a Skinnerian black box stimulus/response. The complexity of the functions inside the box are neither here nor their. The steps are essentially the same. Stimulus -> black box -> action.
Or is will an even less definitive spiritual device attached directly to the function of the soul, or may even be synonymous with the soul. This stacks up well with many religions that profess a sense of responsibility/divine retribution/justice for transgressions against the laws of the univers or a particular diety's code of conduct. Somewhere we must have a definitive agency to act/think, or there is no justice in said justice, it would simply be punishment of the the ignorant, like whipping "dumb animal".
well I suppose enough rambling,
Cheers,
Russ
