“Man is said to be a reasoning animal. I do not know why he has not been defined as an affective or feeling animal. Perhaps that which differentiates him from other animals is feeling rather than reason.”

“The faculty by which man is differentiated from the lower animals is his reasoning power. But the devout believer renounces reason, refuses to explain the things which surround him, the innumerable natural phenomena, because his religious faith is enough for him. The brain loses the habit of thinking; and this religious sottishness hurls mankind back into animalism.”

“Men are rather reasoning than reasonable animals, for the most part governed by the impulse of passion.”

“Man has been called the reasoning animal but he could with greater truthfulness be called the creature of suggestion. He is reasonable, but he is to a greater extent suggestible.”

“I used to say the only reason why I didn’t eat meat was to be healthy, but I would be lying if I said that now, knowing the horrible things they do to the animals. Any person who has a heart for animals and knew how they are treated would be vegan.”

“Man is a reasoning animal.”
Rationale enim animal est homo.

“[Concerning the love La Fontaine felt for animals] He follows their emotions, he represents their reasonings, he becomes tender, he becomes gay, he participates in their feelings. The factis, he lived in them. […] The animals contain all the materials of man-sensations, judgments, images.”

“Man is a two-footed reasoning animal.”
HOMO EST ANIMAL BIPES RATIONALE

“Evolution is not finished; reason is not the last word nor the reasoning animal the supreme figure of Nature. As man emerged out of the animal, so out of man the superman emerges.”

“One is tempted to define man as a rational animal who always loses his temper when he is called upon to act in accordance with the dictates of reason.”
