Use "occasionalist" in a sentence
"Blair is what political historians call an "occasionalist"."
"It can be gathered from isolated statements like the one above and the fact that after the Incoherence al-Ghazâlî wrote books where he maintained a distinctly occasionalist cosmology (al-Ghazâlî 1962) and others like the 35th book of his Revival or the Niche of Lights, where he uses language that is explicitly causalist."
"Given that there will never be a break in God's habit, an occasionalist universe will always remain indistinguishable from one governed by secondary causality."
