Many theists seem to think in black-white absolutes – they use words such as 'all', 'none', 'every', 'only', 'never', 'always', 'forever', 'eternity', 'proof', and 'disproof'. If the apologists had not shunned any question of 'infinity' so as to make room for an 'unmoved first mover', many theists would be talking of 'infinity'.
Categorical thinking is prone to logical error – a single exception to a categorical statement negates the statement. Why, then, do so many theists think and speak categorically? These categorical thinkers have an emotional need for certainty, and preachers promise them certainty. Many theists also seem to lack that inner sense of logical discrepancy that sets "wait a minute, that doesn't make sense!" alarms ringing in many of us.
Their categorical thinking shows up in:
● insistence that moral absolutes were dictated by God,
● insistence that atheists must disprove God's existence or failure to do so proves that God exists,
● insistence that God must exist because some unrelated reality does exist (sunsets, beauty, love, etc),
● insistence that theologians and apologists have 'proved' God's existence
● insistence that biological complexity 'proves' that macroevolution could only have arisen through the agency of God (aka, the designer)
● and so on.
The burden of proof lies with the claimant, so it is not up to atheists to disprove God's existence. This is particularly true since it is not logically possible to disprove a negative. If theists ask for this, then tell them where to put their request . . .
