Why is Zen/Chan thought to be more related to Buddhism than to Taoism?

Taoism is innately Chinese and predates Buddhism by at least one thousand years. The Tao Te Ching is attributed to Lao Tze (500 BC) and Zen Buddhism to Tamo (5th century). Early Taoism resembles ancient nature worship and the religious practices of many other early societies. Taoism and Buddhism merged in peoples' minds much later. Tao Tze and Tamo (and even Lao Tze's student, Confucius) were considered one old, wise teacher.

So to add to what Cameron to saying just so others might be cautious too, we'll in buddha dharma view is of utmost importance. The goal is to get beyond any view but it is very essential. What Cameron is echoing is in my view a fairly common modern misconception based on want to be politically correct and many other reasons perhaps. Say one believes killing animals in the name of God is fine which is true in many religions. From a buddha dharma perspective that will take you away from enlightenment. So clearly all beliefs, all opinions, all religions are not the same. To give nor example say in a religion people believe that killing 100 men in one life will lead to liberation. Now would you Cameron say that that is also a Buddhist view and that both will lead to the same goal?

I hope not. If that is true then you are immediately accepting all beliefs views are not the same and have different consequences. The question then is what views lead to what more importantly what view leads to Buddhist enlightenment. The word enlightenment is not important, what matters is if different views and practices lead to the same age that buddha talked about. And to be clear buddha himself again and again mentioned how his reaching is different from any other. For example he differentiated his teaching even from one of the practices which focused on jhanas merely.

Coming back to zen Methexis had an amazing anwer there. Wow. Thanks. Yes there are many non Buddhists who keep saying it's the same thing because they are ignorant of Buddha's teachings and they are I guess insecured about their own. If it was the same thing there would be some authentic Buddhist master say who recited Bhagavat Gita or Quran but nope. Only self declared unverified Buddhist teachers do that. And even they have not been many as once you start reading the idea of no Self it is different than any other spiritual system and against the most basic belief that we have. That is why it is called spontaneous grasping of self.

It seems to me that most of these 'answers' are based on personal experience, and an attachment to that. If one is shown a great path, one often thinks that it is the only true path, and that others are just lesser, or corrupted versions of that true path. There are many paths up the mountain :)

In reference to Taoist/Buddhist origins of Zen etc.. This is a very difficult one to answer, verifiable evidence is very hard to find from these earlier eras, especially when one considers the above, and human nature, and our ego. Buddhist and Taoist teachings have overlapped in many ways over the centuries, and much of Taoist teachings are misunderstood, and often not known, Taoist have historically tended to be 'retiring' by nature. The situation we have now, is that it is hard to be certain what is just Buddhist and what is just Taoist, there is a great deal of overlap, which is not surprising considering the history of both in China (for instance).

My own personal experience/understanding, having been a student of both Buddhist and Taoist teachers, the similarities are more common than the differences, especially in regard to the path(s) to enlightenment. The differences seem superficial, the core teaching is very similar, and may well be the same way. True or not, they both contain a way to enlightenment, apparently :)

Until we have more proof/evidence of the various claims and counterclaims, it is a moot point. It is also a distraction what is nothing other than an academic discussion, it isn't the path itself, however interesting it is, and it is. It's an interesting discussion but until we have proof one way or the other, but I'm not holding my breath ;)

Truth is truth. Buddhism and Taoism are the same in the end, no matter what tradition you come from.

Taoism and Buddhism go hand-in-hand. Taoism is largely about living in balance with existence, which is a manifestation of the middle way. As someone said, Buddhism came as something of an external confirmation of Taoism.

I think that this kind of thinking is rather superficial. The essence of Zen is the teaching that all beings possess a Buddha nature, and that by seeing into one's true nature one attains enlightenment. None of this is a part of Daoism.

In addition, a lot of the similarities between the two are also found in Buddhist Sutras. For example, the extensive use of paradoxical language to cut through conceptual thinking is found in the Diamond Sutra and many other Buddhist texts, not just in Daoist texts like the Dao De Jing, and they are understood in very different ways as well.

This suggestion that Zen/Chan is Taoism tends to come from the Taoists/Chinese nationalists themselves rather than any real Chan teachings. I am from a Chinese Buddhist school of Chan lineage. Before becoming a practicing Buddhist I dabbled in self study of Taoist teachings.

Since historical times, Chinese civilization due to it's great power with respect to it's surrounding neighbors has always carry a deep conceit in their cultural superiority. This naturally extends into the field of philosophy and religions.

The truth is Buddhism is much much deeper than Taoism. Taoism is fairly enlightened no doubt, especially compared to some very unenlightened behaviors from monotheistic religions. But Taoism does not reach the Four Noble Truths, and does not practice the Eightfold Noble Path. Hence the depth of their wisdom is comparable to other Indian religious spiritual traditions such as Hinduism. But it is not at the level of Buddhism.

In any case, the Taoists out of conceit, tend to claim superiority over Buddhism without actually understanding it. They have even historically claimed that Buddha was Laozi, and even created scriptures to assert this narrative. Essentially they are appealing to Chinese nationalism to maintain support.

The story unfolds in China as Buddhism appears on the scene and is accepted by the Chinese population as a “simplified version of Taoism” that the Western barbarians (subcontinent Indians and Central Asians, e.g. Tibetans, et al.) could understand.

This is not to say Taoism is bad. There are many good things about Taoism. Their contribution to Traditional Chinese Medicine is probably one of the most important contribution. But to claim that Chan Buddhism is a form of Taoism is to give Taoism far too much credit.
