Who are the philosophers past their think-by dates?
Aristotle  -  ancient Greece. Said animals are below humans because only humans can reason; therefore, we can use animals without consideration we’d give to people. 
Aquinas  -  medieval. Said animals cannot reason; therefore, people can use them as they wish. His thinking became Catholic doctrine. 
Descartes  -  renaissance. Said animals are automata and only humans have minds and souls; therefore only humans deserve compassion. 
Animals cannot argue back, so had to put up with this.
