Rabbi Jonathan Sacks

But why, in that case, did Isaac love Esau? Did he not know about Rebecca’s oracle? Had she not told him about it? Besides, did he not know that Esau was wild and impetuous? Can we really take literally the proposition that Isaac loved Esau because "he had a taste for wild game," as if his affections were determined by his stomach, by the fact that his elder son brought him food he loved?
