Pick 1) Roger Scruton's "Conservative Texts : An Anthology". 2) Russel Kirk's "The Conservative Mind : From Burke to Eliot". You'll get n numbers of legendary Conservatives and their views. Not all of them will sound equally convincing to you. Pick someone of your own choice.
Fiercest attack on Modernity & Rationalism in recent times comes from a stream of scholars : Perennialists. Google Philosophia Perennis. You'll get names like Guenon, Coomaraswamy, Schuon & Julius Evola. Hypnotic & Extremely tough Authors.
Caveat : They believe in intellectual version of Sarva Dharma Sambhava. Take it with a pinch of salt. But consider their overall views on Traditions, Ritual & Modernity.
You can also try Ancient/Medieval religious saints like Aquinas & Augustine. Caveat : They're obviously Christian. Relax. Understand the depth of God, Belief & Religion against the Rationalists.
Economists from Hayek & Mises to Friedman & Sowell have also argued against many liberal ideas. Sowell tops them. Caveat : Don't become Ultra Pro Capitalist. While Socialism is an assault on Family, Capitalism is an assault on Ecology. Both are Non-Dharmika. Try to have balance.
Literature also can be a great asset in shaping the views. From Chesterton & Lewis to Solzhenitsyn & Dostoevsky. Others like Aldous Huxley, Thomas Carlyle & Ernest Junger.
Don't worry. As you go deeper you'll get more names. John Kekes & Patrick Deneen on Liberalism. R P George & A M Esolen on Marriage. Berlinski & Meyer on Evolution. Alan De Benoist. Yoram Hazony. D B Hart. Ed Feser. Theodore Dalrymple. And Many More. Expand the Horizon.
There's no way one can read all this within a small time frame. So go for Non Negotiables. For me it's Scruton. From Religion to Music. Architecture to Sexual Nature. Political Thought to Scientism. He has written on everything. Read every word written by him.
Caveat : Always remember that you're reading a Western Conservative. Don't start defending Colonialism after reading him/them. But try to learn and master their art in your own favor. Try arguing for Hindu Rituals & Practices that are denigrated.
This list was about Western Conservative tradition. Though there's a lack of quality Indian conservatives, but there do exist fair enough piece of work. From organisation like Voice of India & Gitapress to individuals like Karpatri Swami to Kanchi Parmacharya. Will expand later.
Lastly, Never stop worshipping our own gods. We can never even think of winning this battle unless our gods bless us. Start reading our own shastras. They're the most important set of texts ever written. Have belief in śrīmannārāyaṇa.
